The diameter of a circle is 10 meters. what is the area of the circle? (use 3.14 for and round to the nearest tenth.)
a.31.4 m
b.62.8 m
c.78.5 m
d.125.6 m

Option (c) is correct.

The Area of given circle is 78.5 m²

Step-by-step explanation:

Given : The diameter of a circle is 10 meters.

We have to determine the area of the given circle.

Consider the given circle with diameter 10 meters

Radius is half of diameter

So , Radius = 5 meters

Area of circle =

Thus, Area of circle =

Simplify by putting  π = 3.14

We have,

Area of circle =

Thus, The Area of given circle is 78.5 m²

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
