Calculating Surface Area and Volume of Cylinders

The video tutorial explains the geometric shape of a cylinder, highlighting its three-dimensional nature with length, height, and width. It demonstrates how to calculate the surface area by considering the cylindrical side as a rectangle and the circular top and bottom. The tutorial also covers the calculation of volume by determining the base area and multiplying it by the height. Practical examples with measurements are provided to illustrate these calculations.

What is a defining characteristic of a cylinder when viewed from the top?

• It has a triangular shape.

• It has a square shape.

• It has a circular shape.

• It has a rectangular shape.

How do you calculate the area of a rectangle?

• By dividing its length by its width.

• By multiplying its length by its width.

• By adding its length and width.

• By subtracting its width from its length.

What is the formula to find the area of a circle?

• Area equals pi times diameter squared.

• Area equals pi times diameter times radius.

• Area equals pi times radius squared.

• Area equals diameter times radius.

If the diameter of a circle is 7 cm, what is the radius?

• 3 cm

• 3.5 cm

• 7 cm

• 14 cm

How do you calculate the volume of a cylinder?

• By multiplying the base area by the height.

• By adding the base area and the height.

• By subtracting the height from the base area.

• By dividing the base area by the height.
