Surface Area of Cylinders Practice

Front

What is the formula for the surface area of a cylinder?

Back

The surface area (SA) of a cylinder is given by the formula: SA = 2πr(h + r), where r is the radius and h is the height.

Front

How do you calculate the radius from the diameter of a cylinder?

Back

The radius (r) is half of the diameter (d). So, r = d/2.

What is the surface area of a cylinder with a diameter of 18 in and a height of 15 in?

Back

1,356.48 in².

Front

What is the total surface area of a cylinder to the nearest square inch if the calculated area is 1300.5 in²?

Back

1301 in².

Front

If a cylinder has a radius of 1 in and a height of 2 in, what is its surface area?

Back

18.84 in².

What is the surface area of a cylinder with a radius of 5 cm and a height of 10 cm?

Back

314.16 cm².

Front

How do you round a surface area answer to the nearest hundredth?

Back

Look at the third decimal place: if it's 5 or more, round up the second decimal place by one; if it's less than 5, keep the second decimal place the same.
