A cylinder with a radius of 4cm and a height of 2cm has a volume of 100.53cm3
Volume = pi*22*5 cubic cm
20 pie cm^3
The formula for the volume of a cylinder is Pi x r^2 x height. So this cylinder's volume is Pi (2cm)^2 x 5cm = 62.83 cubic cm
The volume of the cylinder is: 15.7 cm3
32.56
62.8 (pi times radius squared times height (3.14* 2 squared=12.56 then 12.56 times 5= 62.8)
The displaced liquid volume is equal to the volume of the cylinder. The volume of the cylinder is πr^2h, so in this case it is π(2cm)^2(4cm) = 16π cm^3. The volume displaced is equal to the rise in the liquid level in the graduated cylinder. Using the formula for the volume of the liquid in a cylinder (πr^2h), we can solve for the height (h). The rise in the liquid level will be approximately 1.06 cm.
A cylinder whose radius is 2cm and height is 8cm has a total surface area of approximately 125.66cm2 {ADDED} To explain that further, the formula is pi*r^2 X h where r is the radius and h the height.
The volume of a sphere with a radius of 2cm is about 33.5cm3
The lateral area of a cylinder with a diameter of 10cm and height of 2cm is approximately 62.83cm2
The volume is 4.19 cm3
The volume of a cube is calculated by multiplying the length, width, and height of the cube. In this case, all sides of the cube are 2cm. Therefore, the volume of the cube would be 2cm x 2cm x 2cm = 8 cubic centimeters.
