Find the radius of a circle with an area of 27 pie cm

Area of a circle is = PI x r^2

Area = 27 PI

This means the radius would be the square root of 27:

√27 = 3√3

The answer is F.

F 3 sqrt(3)

Step-by-step explanation:

The area of a circle is given by

A = pi*r^2

We know the area is 27*pi

27 *pi = pi*r^2

Divide each side by pi

27 *pi/pi = pi/pi*r^2

27 = r^2

Take the square root of each side

sqrt(27) = sqrt(r^2)

sqrt(9*3) = r

sqrt(9) sqrt(3) = r

3sqrt(3) =r

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
