Answer:_______________

The diameter of a circular park is 161 m. Find the cost of fencing it at 8 per meter.

Answer: 4048

SOLUTION 1 :

Given,

Diameter of the wheel = 161m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~161~~²³

= 22 x 23

= 506 m.

Cost of fencing for one meter = 8

Cost of fencing for 506 meters = 506 x 8 = 4048

Hence, the cost of fencing the circular park is 4048.

The diameter of a circular park is 168 m. Find the cost of fencing it at 9 per meter.

Answer: 4752

SOLUTION 1 :

Given,

Diameter of the wheel = 168m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~168~~²⁴

= 22 x 24

= 528 m.

Cost of fencing for one meter = 9

Cost of fencing for 528 meters = 528 x 9 = 4752

Hence, the cost of fencing the circular park is 4752.

The diameter of a circular park is 49 m. Find the cost of fencing it at 6 per meter.

Answer: 924

SOLUTION 1 :

Given,

Diameter of the wheel = 49m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 49⁷

= 22 x 7

= 154 m.

Cost of fencing for one meter = 6

Cost of fencing for 154 meters = 154 x 6 = 924

Hence, the cost of fencing the circular park is 924.

The diameter of a circular park is 140 m. Find the cost of fencing it at 8 per meter.

Answer: 3520

SOLUTION 1 :

Given,

Diameter of the wheel = 140m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~140~~²⁰

= 22 x 20

= 440 m.

Cost of fencing for one meter = 8

Cost of fencing for 440 meters = 440 x 8 = 3520

Hence, the cost of fencing the circular park is 3520.

The diameter of a circular park is 154 m. Find the cost of fencing it at 4 per meter.

Answer: 1936

SOLUTION 1 :

Given,

Diameter of the wheel = 154m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~154~~²²

= 22 x 22

= 484 m.

Cost of fencing for one meter = 4

Cost of fencing for 484 meters = 484 x 4 = 1936

Hence, the cost of fencing the circular park is 1936.

The diameter of a circular park is 189 m. Find the cost of fencing it at 9 per meter.

Answer: 5346

SOLUTION 1 :

Given,

Diameter of the wheel = 189m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~189~~²⁷

= 22 x 27

= 594 m.

Cost of fencing for one meter = 9

Cost of fencing for 594 meters = 594 x 9 = 5346

Hence, the cost of fencing the circular park is 5346.

The diameter of a circular park is 147 m. Find the cost of fencing it at 9 per meter.

Answer: 4158

SOLUTION 1 :

Given,

Diameter of the wheel = 147m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~147~~²¹

= 22 x 21

= 462 m.

Cost of fencing for one meter = 9

Cost of fencing for 462 meters = 462 x 9 = 4158

Hence, the cost of fencing the circular park is 4158.

The diameter of a circular park is 182 m. Find the cost of fencing it at 4 per meter.

Answer: 2288

SOLUTION 1 :

Given,

Diameter of the wheel = 182m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~182~~²⁶

= 22 x 26

= 572 m.

Cost of fencing for one meter = 4

Cost of fencing for 572 meters = 572 x 4 = 2288

Hence, the cost of fencing the circular park is 2288.

The diameter of a circular park is 196 m. Find the cost of fencing it at 7 per meter.

Answer: 4312

SOLUTION 1 :

Given,

Diameter of the wheel = 196m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~196~~²⁸

= 22 x 28

= 616 m.

Cost of fencing for one meter = 7

Cost of fencing for 616 meters = 616 x 7 = 4312

Hence, the cost of fencing the circular park is 4312.

10)

The diameter of a circular park is 154 m. Find the cost of fencing it at 5 per meter.

Answer: 2420

SOLUTION 1 :

Given,

Diameter of the wheel = 154m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~154~~²²

= 22 x 22

= 484 m.

Cost of fencing for one meter = 5

Cost of fencing for 484 meters = 484 x 5 = 2420

Hence, the cost of fencing the circular park is 2420.
