Question

2. Find the area of the circle. Round to the nearest tenth.

A.113.1
B.37.7
C.18.8
D.28.3

Answer 1

The answer is D.

The formula to find area of a circle is : πr²

Here, we are given the diameter, but we need the radius. Always remember that the radius is always half the diameter.

Let's find the area.

• A = π × r²
• A = 3.14 × (3)²
• A = 3.14 × 9
• A = 28.26
• A ≈ 28.3
