Question

The radius of a circle is 8 meters.

The diameter of the circle is .
The formula for circumference is C = πd or C = 2πr.

The circumference of the circle is approximately .

Answer 1

Diameter is 16 meters and Circumference of the circle is approximately 50.2 meters

Explanation:

If radius is 8 m,

the diameter is 2 radius = 2*8 = 16 m

Circumference C = \pi d

= (22/7)*16

= 352/7

≈ 50.2 m

Answer 2

Diameter is 16 meters and Circumference of the circle is approximately 50.3 meters

Explanation:

If radius is 8 m,

the diameter is 2 radius = 2*8 = 16 m

Circumference C =
`\pi d`

= (22/7)*16

= 352/7

≈ 50.3 m
