Question

What is the area of a circle with diameter of 6x? (Use 3.14 for π.)

A) 6x
B) 18.84x2
C) 26.28x2
D) 28.26x2

Answer 1

it is D

Explanation:

Answer 2

The equation for area of a circle is
`\pi r^(2)`

So with a diameter of 6, the circle has a radius of 3x.

Area =
`\pi`(9
`x^(2)`) = 28.26
`x^(2)`
