A. 20π cubic centimeters B. 60π cubic centimeters C. 40π cubic centimeters D. 30π cubic centimeters 相关知识点: 试题来源: 解析 C。圆柱体积=底面积×高,底面积=π×半径的平方,π×2×2×5=20π 立方厘米。反馈 收藏
In most cases, you will need only two of the below quantities: height; volume; longest diagonal; base surface area; lateral surface area; total surface area; or surface-to-volume ratio. This radius of a cylinder calculator is a handy tool that can compute the parameters of right circular ...
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...
A. 20π cm² B. 24π cm² C. 28π cm² D. 32π cm² 相关知识点: 试题来源: 解析 C。圆柱体表面积 = 2×π×半径² + 2×π×半径×高,半径为 2cm,高为 6cm 的圆柱体表面积为 2×π×2² + 2×π×2×6 = 8π + 24π = 28π cm²。选项 A 计算错误。选项 B ...
15. A cylinder in which the radius equals the height contains one largest possible spher e. How much volume is inside of the cylinder, but outside of the sphere? Because r=h, give your answer in terms of r.d ha⋅1/6πr^3 台1/3πr^3 3cnr3 3 d.πr3 6 e. There is not ...
A cylinder has a radius of 4 cm and a height of 10 cm. What's the volume? A. 160π cm³ B. 80π cm³ C. 40π cm³ D. 120π cm³ 相关知识点: 试题来源: 解析 A。解析:圆柱体积等于底面积乘以高,底面积是π乘以半径的平方,即 16π平方厘米,体积为 16π×10=160π立方...
试题来源: 解析 A。圆柱体体积 = π×半径²×高,半径为 3cm,高为 5cm 的圆柱体体积为 π×3²×5 = 45π cm³。选项 B 计算错误。选项 C 是π×3² = 9π cm²,是底面积。选项 D 是 3³π = 27π cm³,计算错误。反馈 收藏 ...
