Question

If the circumference of a wheel is 94 cm what is its approximate diameter

Answer 1

Hey there :)

We know the formula for the circumference of a circle:
Circumference = 2$\pi$ × radius 
2 × radius = diameter
Circumference = $\pi$ × diameter

We are given:
Circumference = 94

Apply the formula:
94 = $\pi$d

Divide by $\pi$ on either side to isolate d and find its value

$\frac{94}{ \pi } = \frac{ \pi d}{ \pi }$
$\frac{94}{ \pi } = d$

d ≈ 29.9 cm → Your answer
