if C=12TT what is the area of the circle

Question

a.144TT
b.24TT
c.12TT
d.36TT

Answer 1

The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle.

Given that C = 12r, we can determine the radius by dividing the circumference by 2π.

r = C / 2π
r = 12 / 2π
r = 6

Now that we have the radius, we can calculate the area of the circle:

A = π(6^2)
A = π(36)
A = 36π

So, the correct answer is d. 36π.
