Question 1

What is circumference, how do you calculate it?

Answer 1

Circumference is the distance around the circle. To calculate circumference, you do diameter multiplied by pi.

Question 2

What is diameter, and how do you calculate it?

Answer 2

Diameter is the distance across the circle through the center. To calculate diameter, you do radius multiplied by 2.

Question 3

What is radius, and how do you calculate it?

Answer 3

Radius is the distance from the center of the circle to the edge. To calculate radius, you do diameter divided by 2.

Question 4

How do you calculate the area of a circle?

Answer 4

To calculate the area of a circle, you do pi multiplied by radius squared.

Question 5

How do you calculate the volume of a circle?

Answer 5

To calculate the volume of a circle, you do pi x radius squared x height.

Question 6

How do you find the curved surface area of a cylinder? How do you find the total surface area?

Answer 6

To find the curved SA of a cylinder, you do 2 x pi x radius x height. To find the total SA, you do 2 x pi x radius2 + 2 x pi x radius x height.
