Question

a can of beans has a surface area 370cma can of beans has a surface area 370cm^(2) its height is 20cm. what is the radius of the circular top its height is 20cm. what is the radius of the circular top

Answer 1

To find the radius of the circular top of the can of beans, you can use the formula for the surface area of a cylinder and solve for the radius.

Step-by-step explanation:

To find the radius of the circular top, we need to first calculate the surface area of the can. Since the surface area is given as 370 cm² and the height is 20 cm, we can use the formula for the surface area of a cylinder: 2πr² + 2πrh = 370. Substituting the known values into the equation, we have 2πr² + 2π(20 cm)(r) = 370. Simplifying, we get 2πr² + 40πr = 370. We can solve this equation using algebra or a graphing calculator to find the value of r that makes the equation true.
