Question

what is the area of a circle with a diameter of 15.8 cm? use 3.14 for pi and round your final answer to the nearest hundredth. enter your answer in the box.

Answer 1

The formula to calculate the area of a circle is given by: A = π * r^2, where r is the radius of the circle.

Given the diameter of 15.8 cm, we can calculate the radius by dividing the diameter by 2: r = 15.8 cm / 2 = 7.9 cm

Plugging the value of the radius into the formula: A = π * 7.9^2 = 3.14 * 62.41 = 196.0794 cm^2

Rounding the answer to the nearest hundredth, the area of the circle with a diameter of 15.8 cm is approximately 196.08 cm^2.

Answer 2

196.1 cm^2

Explanation:

The area of a circle is given by Area = πr^2

R is (15.8 cm)/2 = 7.9 cm

Area = (3.14)*(7.0cm)^2

Area = 196.1 cm^2
