Question

What is the best approximation for the circumference of a circle with a diameter of 300 ft?

Use 3.14 to approximate pi.

235.5 ft

471 ft

942 ft

2826 ft

Answer 1

the formula for circumference is

C=
`\pi`d

where d is the diameter

we are using 3.14 for pi and 300ft for the diameter so we can plug these values in

C = (3.14)(300)

C = 942 ft

your answer should be

942ft

Answer 2

Hello!


`\bf Answer`

The best approximation for the circumference is
`\boxed{ \bf 942~ft.}`

`\bf Explanation`

c = 2
`\pi`r

r = 300 ÷ 2

r = 150


c = 2 × 3.14 × 150

c = 942
