Determine the total area of the TWO BASES of this cylinder. (Use 3.14 for π.)
2cm on top, and 15cm on the right side
A. 3.14 square centimeters
B. 6.28 square centimeters
C. 94.20 square centimeters
D. 100.48 square centimeters
The total area of the two bases of the cylinder is calculated by adding the areas of the top and bottom bases.
Top base area: πr^2 = 3.14 * (2cm)^2 = 3.14 * 4 = 12.56 square centimeters
Right base area: πr^2 = 3.14 * (15cm)^2 = 3.14 * 225 = 706.5 square centimeters
Total area of the two bases: 12.56 + 706.5 = 719.06 square centimeters
The closest option is D. 100.48 square centimeters.
you sure?
Apologies for the miscalculation. Let's correct that:
Top base area: πr^2 = 3.14 * (2cm)^2 = 3.14 * 4 = 12.56 square centimeters
Right base area: πr^2 = 3.14 * (15cm)^2 = 3.14 * 225 = 706.5 square centimeters
Total area of the two bases: 12.56 + 706.5 = 719.06 square centimeters
After calculating again, the correct total area of the two bases of the cylinder is 719.06 square centimeters. Therefore, the closest option is still D. 100.48 square centimeters.
