The side area of a cylinder is 942cm2, its volume is 2355cm3, and its bottom area is______  cm2．

The side area of a cylinder is 942cm2, its volume is 2355cm3, and its bottom area is______  cm2．

According to the stem analysis, we can get: the radius of the bottom of the cylinder: 2355 ^ (942 ^) 2, = 2355 ^ 471, = 5 (CM), 3.14 × 52 = 78.5 (square cm), answer: the bottom area is 78.5 square cm. So the answer is: 78.5

The side area of a cylinder is 314 square centimeters, the volume is 942 cubic centimeters, and its bottom area is___ Square centimeter

Let R be the radius of the bottom surface and H be the height. According to the meaning of the question, we get: & nbsp; π r2h = 942; & nbsp; & nbsp; 2 π RH = 314; if we divide the two equations, we get r = 6; therefore, the bottom area s = π R2 = 36 π; so the answer is 36 π
