Question

A) If the area of a circle is
28.26 cm?, what is the radius of the circle?

Answer 1

To find the radius of the circle, we first need to calculate the radius using the formula for the area of a circle:

Area = π * radius^2

Given that the area is 28.26 cm^2, we can plug this value into the formula and solve for the radius:

28.26 = π * radius^2

To isolate the radius, we divide both sides by π:

radius^2 = 28.26 / π
radius^2 = 9

Taking the square root of both sides, we find:

radius = √9
radius = 3 cm

Therefore, the radius of the circle is 3 cm.
