Question

The diameter of a circle is 10 meters. What is the area of the circle? (Use 3.14 for Pi and round to the nearest tenth.)

31.4 meters squared
62.8 meters squared
78.5 meters squared
125.6 meters squared

Answer 1

Area of a circle=pi*(radius)^2

Diameter=2*radius

=> radius=5 m

Area=3.14*(5)^2=3.14*25=78.5 m^2

Explanation:

Answer 2

Choice 3

Explanation:

A=pi*r squared

Diameter= 10, 10/2= 5

Radius=5

A=pi* (5)^2

A= 78.54...

The area of the circle is 78.5 meters squared.
