Question

Find the area of a circle with a diameter of \color{green}{6}6start color green, 6, end color green.

Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.


*please help me

Answer 1

The area of the circle is 9π

Explanation:

radius = half of diameter

d = 6

r = 6/2 = 3

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 3

a = π * r²

we replace with the known values

a = π * (3)²

a = π * 9²

a = 9π

The area of the circle is 9π
