Calculate the area of a circle with a radius of 3 cm. Use 3.14 for pi, and round your answer to the nearest hundredth.
A- 18.84 cm2
B- 59.16 cm2
C- 29.58 cm2
D- 28.26 cm2
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle.
Given that the radius is 3 cm:
A = 3.14 x (3)^2
A = 3.14 x 9
A = 28.26 cm^2
Therefore, the area of the circle with a radius of 3 cm is 28.26 cm^2. Rounded to the nearest hundredth, the answer is D- 28.26 cm^2.
