The area of each circle is πr^2, where r is the radius.
So for a circle with radius 0.75 inches, the area is π(0.75)^2 = 0.5625π square inches.
There are two circles on the cylinder, one on each side.
So the total area of all the circles is 2 * 0.5625π = 1.125π square inches.
Answer the questions below to find the total surface area of the can.
A cylinder with radius 0.75 inches and height 4 inches. A circle with radius 0.75 inches on each side of a rectangle with width 4 inches.
The area of each circle is exactly ____ π square inches.
There are ____ identical circles in the cylinder.
So the total area of all the circles is ____ π square inches.
