Sagot :
Area of a circle is:
A = pi * r^2
If the diameter is 10 feet, the radius will be half of that or 5.
So:
A = 3.14 * 5^2
Simplify exponent:
A = 3.14 * 25
Multiply:
A = 78.5
A = pi * r^2
If the diameter is 10 feet, the radius will be half of that or 5.
So:
A = 3.14 * 5^2
Simplify exponent:
A = 3.14 * 25
Multiply:
A = 78.5
The area is πr².
The radius r is half the diameter. The diameter is 10 ft so the radius is 5 ft.
[tex]A=\pi \times 5^2=25 \pi[/tex]
The area is 25π ft².
