Question

The diameter of a circle is 15 centimeters.

Using 3.14 as π
, enter the area of the circle, in square centimeters. Round your answer to the nearest HUNDREDTH.

Answer 1

1. 132.67
2. 60
3. 72.67

Explanation:

the vertices of the rectangle lie on the circumference of the circle

We know that our diameter of the circle is equal to 13 cm, radius of the circle is half the diameter

the radius of the circle = 1/2 (13) = 6.5 cm

1. 3.14 × (6.5)² = 132.67 cm²

2. 12 × 5 = 60 cm²

3. 132.67 - 60 = 72.67 cm²

1. 132.67
2. 60
3. 72.67
