Answer:_______________

Find the circumference of a circle whose diameter is 105cm

Answer: 330cm

SOLUTION 1 :

Given,

d = 105

circumference of the circle = πd

= $\frac{22}{7}$ x 105

= 22 / 7 x ~~105~~¹⁵

= 330

Circumference of circle is 330 cm.

Find the circumference of a circle whose diameter is 98cm

Answer: 308cm

SOLUTION 1 :

Given,

d = 98

circumference of the circle = πd

= $\frac{22}{7}$ x 98

= 22 / 7 x 98¹⁴

= 308

Circumference of circle is 308 cm.

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 84cm

Answer: 264cm

SOLUTION 1 :

Given,

d = 84

circumference of the circle = πd

= $\frac{22}{7}$ x 84

= 22 / 7 x 84¹²

= 264

Circumference of circle is 264 cm.

Find the circumference of a circle whose diameter is 35cm

Answer: 110cm

SOLUTION 1 :

Given,

d = 35

circumference of the circle = πd

= $\frac{22}{7}$ x 35

= 22 / 7 x 35⁵

= 110

Circumference of circle is 110 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 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 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 140cm

Answer: 440cm

SOLUTION 1 :

Given,

d = 140

circumference of the circle = πd

= $\frac{22}{7}$ x 140

= 22 / 7 x ~~140~~²⁰

= 440

Circumference of circle is 440 cm.

Answer: 132cm

SOLUTION 1 :

Given,

d = 42

circumference of the circle = πd

= $\frac{22}{7}$ x 42

= 22 / 7 x 42⁶

= 132
