If the side area of a cylinder is 50.24 square centimeter and the height is equal to the bottom radius, what is the surface area?

If the side area of a cylinder is 50.24 square centimeter and the height is equal to the bottom radius, what is the surface area?


Let the radius of the bottom of the cylinder be r cm, then the height is r cm. According to the formula of the side area of the cylinder, we can get: 3.14 × 2 × R × r = 50.24, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 6.28r2 = 50.24, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp
