What is the total surface area of this eraser? Your answer should have two decimal places.
To find the total surface area of the eraser, we need to calculate the surface area of each section separately and then add them together.
The eraser is in the shape of a cylinder with a radius of 1.5 cm and a height of 5.5 cm. The formula to calculate the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Surface Area = 2π(1.5)^2 + 2π(1.5)(5.5)
Surface Area = 2π(2.25) + 2π(8.25)
Surface Area = 4.5π + 16.5π
Surface Area = 21π
The surface area of the eraser is approximately 65.97 cm².
