Chapter 1: Q16. (page 28)

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

The diameter is 25 feet.

Short Answer

Expert verified

The area of the circle is 490.6ft2.

Step by step solution

01

Step 1. Given information.

A circle with diameter 25 feet.

02

Step 2. Concept used.

The area of a circle with radiusr is given by A=蟺r2.

03

Step 3. Calculations.

Since the radius is half of the diameter, so, the radius is 12.5 feet.

A=蟺r2=3.14脳12.52=3.14脳156.25=490.625

Rounding off to the nearest tenth, we get,

A=490.6ft2

Thus, the area of the circle is 490.6ft2.
