Question

Find the area of the circle pictured above.
Round your answer to the nearest tenth

Answer 1

A ≈ 314.2 units

Explanation:

To find the area of the circle, we will use the given formula. We are given the diameter (d), 20, and the radius (r) is half of the diameter. 20 units / 2 = 10 units for our radius (r).

A = πr²

A = π(10)²

A ≈ 314.15927

Now, we are asked to round to the nearest tenth.

A ≈ 314.2 units
