Answer:_______________

The diameter of a circular park is 70 m. Find the cost of fencing it at 8 per meter.

Answer: 1760

SOLUTION 1 :

Given,

Diameter of the wheel = 70m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 70¹⁰

= 22 x 10

= 220 m.

Cost of fencing for one meter = 8

Cost of fencing for 220 meters = 220 x 8 = 1760

Hence, the cost of fencing the circular park is 1760.

The diameter of a circular park is 56 m. Find the cost of fencing it at 6 per meter.

Answer: 1056

SOLUTION 1 :

Given,

Diameter of the wheel = 56m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 56⁸

= 22 x 8

= 176 m.

Cost of fencing for one meter = 6

Cost of fencing for 176 meters = 176 x 6 = 1056

Hence, the cost of fencing the circular park is 1056.

The diameter of a circular park is 175 m. Find the cost of fencing it at 5 per meter.

Answer: 2750

SOLUTION 1 :

Given,

Diameter of the wheel = 175m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~175~~²⁵

= 22 x 25

= 550 m.

Cost of fencing for one meter = 5

Cost of fencing for 550 meters = 550 x 5 = 2750

Hence, the cost of fencing the circular park is 2750.

The diameter of a circular park is 182 m. Find the cost of fencing it at 5 per meter.

Answer: 2860

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 = 5

Cost of fencing for 572 meters = 572 x 5 = 2860

Hence, the cost of fencing the circular park is 2860.

The diameter of a circular park is 168 m. Find the cost of fencing it at 4 per meter.

Answer: 2112

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 = 4

Cost of fencing for 528 meters = 528 x 4 = 2112

Hence, the cost of fencing the circular park is 2112.

The diameter of a circular park is 182 m. Find the cost of fencing it at 7 per meter.

Answer: 4004

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 = 7

Cost of fencing for 572 meters = 572 x 7 = 4004

Hence, the cost of fencing the circular park is 4004.

The diameter of a circular park is 105 m. Find the cost of fencing it at 7 per meter.

Answer: 2310

SOLUTION 1 :

Given,

Diameter of the wheel = 105m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~105~~¹⁵

= 22 x 15

= 330 m.

Cost of fencing for one meter = 7

Cost of fencing for 330 meters = 330 x 7 = 2310

Hence, the cost of fencing the circular park is 2310.

The diameter of a circular park is 84 m. Find the cost of fencing it at 8 per meter.

Answer: 2112

SOLUTION 1 :

Given,

Diameter of the wheel = 84m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 84¹²

= 22 x 12

= 264 m.

Cost of fencing for one meter = 8

Cost of fencing for 264 meters = 264 x 8 = 2112

Hence, the cost of fencing the circular park is 2112.

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 161 m. Find the cost of fencing it at 7 per meter.

Answer: 3542

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 = 7

Cost of fencing for 506 meters = 506 x 7 = 3542

Hence, the cost of fencing the circular park is 3542.
