To find the radius of each can, you would measure the diameter of the circular base of the can and then divide it by 2 to get the radius. In this case, since you have the diameter of the circular base of the can, which is 5 3/4 inches, you would divide this by 2 to get the radius:
Radius = (5 3/4 inches) / 2 = 2 7/8 inches
Now that you have the radius, you can use the formula for the surface area of a cylinder to find the surface area of each can. The formula for the surface area of a cylinder is:
Surface Area = 2πr² + 2πrh
Given that the radius (r) is 2 7/8 inches and the height (h) is not provided, you can find the approximate surface area of each can using 3.14 as the value of pi.
A manufacturer produces cylindrical cans of fruit as shown. To use a formula to find the surface area of each can, you need to find the radius of each can. What step should you perform to find the radius of each can? Use a formula to find the surface area of each can. Use 3.14 for pi.
The surface area of each can is about V in. squared.
Solve for V.
Radius = 4 3/4
Base = 5 3/4
