Answer:_______________

Find the circumference of a circle whose diameter is 147cm

Answer: 462cm

SOLUTION 1 :

Given,

d = 147

circumference of the circle = πd

= $\frac{22}{7}$ x 147

= 22 / 7 x ~~147~~²¹

= 462

Circumference of circle is 462 cm.

Find the circumference of a circle whose diameter is 91cm

Answer: 286cm

SOLUTION 1 :

Given,

d = 91

circumference of the circle = πd

= $\frac{22}{7}$ x 91

= 22 / 7 x 91¹³

= 286

Circumference of circle is 286 cm.

Find the circumference of a circle whose diameter is 63cm

Answer: 198cm

SOLUTION 1 :

Given,

d = 63

circumference of the circle = πd

= $\frac{22}{7}$ x 63

= 22 / 7 x 63⁹

= 198

Circumference of circle is 198 cm.

Find the circumference of a circle whose diameter is 133cm

Answer: 418cm

SOLUTION 1 :

Given,

d = 133

circumference of the circle = πd

= $\frac{22}{7}$ x 133

= 22 / 7 x ~~133~~¹⁹

= 418

Circumference of circle is 418 cm.

Find the circumference of a circle whose diameter is 112cm

Answer: 352cm

SOLUTION 1 :

Given,

d = 112

circumference of the circle = πd

= $\frac{22}{7}$ x 112

= 22 / 7 x ~~112~~¹⁶

= 352

Circumference of circle is 352 cm.

Find the circumference of a circle whose diameter is 119cm

Answer: 374cm

SOLUTION 1 :

Given,

d = 119

circumference of the circle = πd

= $\frac{22}{7}$ x 119

= 22 / 7 x ~~119~~¹⁷

= 374

Circumference of circle is 374 cm.

Find the circumference of a circle whose diameter is 77cm

Answer: 242cm

SOLUTION 1 :

Given,

d = 77

circumference of the circle = πd

= $\frac{22}{7}$ x 77

= 22 / 7 x 77¹¹

= 242

Circumference of circle is 242 cm.

Find the circumference of a circle whose diameter is 49cm

Answer: 154cm

SOLUTION 1 :

Given,

d = 49

circumference of the circle = πd

= $\frac{22}{7}$ x 49

= 22 / 7 x 49⁷

= 154
