Find the area of the circle with a diameter of 8 cm. Use pi=3.14
Round your answer to the nearest hundredth A = pi r exponent of 2
First, we need to find the radius of the circle, which is half of the diameter:
Radius = Diameter / 2
Radius = 8 cm / 2 = 4 cm
Next, we can plug the radius into the formula for the area of a circle:
A = πr^2
A = 3.14 x (4 cm)^2
A = 3.14 x 16 cm^2
A = 50.24 cm^2
Therefore, the area of the circle with a diameter of 8 cm is approximately 50.24 square centimeters.
