What is the volume of a cylinder with radius of 3 and height of 8cm?
V = 226.195 cm3
What is the volume if the radius is 3 and the height is 8?
I'm assuming you are asking about a cylinder. The volume of a cylinder is the area of the base times the height. The base is a circle so its area is pi*r^2. We get V=height*pi*radius*radius = 8*pi*3*3 = 72*pi which is about 226.195
What is the volume of A cylinder has a radius of 3 cm and height of 3 cm?
Calculate the area of one circular face of the cylinder [pi (r2)], then multiply by the height of the cylinder. The answer will be approximate as pi is neither a terminating or repeating decimal. V=volume r=radius h=height V=[pi(r2)] h = [pi(32)] 3 =[pi (9)] 3 =(28.274) 3 =84.82 cm3 So, the volume of a cylinder with a radius and height of 3 cm will be approximately 84.82 cm3.
What is the volume of a cylinder whose radius is 3 feet and whose height is 7 feet?
Volume of a cylinder = πr²hV= 3.14159 × (3)² × 7V= 197.92 ft³
What is the ratio of the radii of a cone and a cylinder if they have the same volume and height?
Let the cylinder have radius R and height h Let the cone have radius r and same height h Then: Volume cylinder = πr²h Volume cone = ⅓πR²h If the volume are equal: ⅓πR²h = πr²h → ⅓R² = r² → R² = 3r² → R = √3 r → ratio radii cone : cylinder = 1 : √3
