Answer:
25π/4 square meters
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius of the circle.
The radius is half the diameter, so is (1/2)(5 m) = 5/2 m. Using this in the area formula, we find the area to be ...
A = π(5/2 m)² = (25/4)π m²
The area of the circle is 25π/4 square meters.
__
As a decimal, that is 6.25π square meters.
Answer:
A = 6.25π
Step-by-step explanation:
Area of a circle:
A = πr²
Given:
d = 5
To find r, divide d by 2:
r = d/2
r = 5/2
r = 2.5
Area of a circle:
A = πr²
A = π2.5²
A = 6.25π
