Determine the total area of the TWO BASES of this cylinder. (Use 3.14 for π.) 2cm high, 15cm wide
3.14 square centimeters
3.14 square centimeters
6.28 square centimeters
6.28 square centimeters
94.20 square centimeters
94.20 square centimeters
100.48 square centimeters
which one of the options is the answer?
The formula for the area of a circle is A = πr^2, where r is the radius. In this case, the radius of the base of the cylinder is half the width, so the radius is 15/2 or 7.5 cm.
Calculating the area of one base:
A = 3.14 x (7.5)^2 = 3.14 x 56.25 = 176.625 square cm
Since there are two bases, the total area of both bases is:
2 x 176.625 = 353.25 square cm
Therefore, the total area of the two bases of the cylinder is 353.25 square centimeters.
