Question

If a circle has a diameter of 30 meters, which expression gives its area in square meters?

A.15^2 x π
B. 30 x π
C. 30^2 x π
D. 15 x π

Answer 1

A.15^2 x π (APEX)

Explanation:

Answer 2

Area of a circle is given by
`\pi r^(2)` where
`r` is the radius

Radius of a circle is half of the diameter

We have the diameter 30 meters, so the radius is 30÷2=15 meters

Area of the circle =
`\pi (15)^(2)`

Note: The option given doesn't show the
`\pi` symbol but it seems like the correct answer is option A
