A cylinder has a radius of 4 cm and a height of 10 cm. What's the volume of the cylinder? A. 160π cm³ B. 120π cm³ C. 80π cm³ D. 16π cm³ 相关知识点: 试题来源: 解析 A。本题考查圆柱体体积的计算。圆柱体体积等于底面积乘以高,底面积是πr²,所以体积是π×4...
A cylinder has a radius of 3 cm and a height of 10 cm. What is the volume of the cylinder? (Use π≈ 3.14) A. 282.6 cubic cm B. 188.4 cubic cm C. 94.2 cubic cm D. 28.26 cubic cm 相关知识点: 试题来源: 解析 A。此题考查圆柱体体积计算。圆柱体体积 = π×半径²×高,...
解析 A If the height h of a cylinder equals the circumference of the cylinder with radius r, then h=2π r, so r=(2π). Hence:Volume of cylinder =π r^2h=π( (2π))^2h=π( (h^2)(4π^2))h=(π h^3)(4π^2)=(h^3)(4π)...
