Question

A circle has a circumference of 907.46 units. What is the diameter of the circle?

Answer 1

Answer:d≈288.85

C Circumference

907.46

Explanation:

Using the formulas

C=2πr

d=2r

Solving ford

d=C

π=907.46

π≈288.85349

Answer 2

288.85 units (nearest hundredth)

Explanation:

circumference of a circle =
`\pi`d (where d is the diameter)

Given circumference = 907.46

⇒ 907.46 =
`\pi`d

⇒ d = 907.46 ÷
`\pi` = 288.85 units (nearest hundredth)
