Chapter 11 Flashcardizz Review

Front

What is the formula for calculating the surface area of a composite figure?

Back

The surface area of a composite figure is found by calculating the surface area of each individual shape that makes up the figure and then summing those areas.

Front

Calculate the surface area of a rectangular prism with length 10 cm, width 5 cm, and height 4 cm.

Back

Surface Area = 2lw + 2lh + 2wh = 2(10)(5) + 2(10)(4) + 2(5)(4) = 100 + 80 + 40 = 220 cm².

Front

What is the area of a circle with a radius of 5 cm?

Back

Area = πr² = π(5)² = 25π cm².

Front

How do you find the area of a shaded region in a composite shape?

Back

To find the area of a shaded region, calculate the area of the entire shape and subtract the area of the unshaded part.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

Calculate the area of a triangle with a base of 8 m and a height of 5 m.

Back

Area = 1/2 * 8 * 5 = 20 m².

Front

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = length * width * height.

Front

Find the volume of a rectangular prism with dimensions 4 cm x 5 cm x 2 cm.

Back

Volume = 4 * 5 * 2 = 40 cm³.

Front

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

Back

Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

Calculate the surface area of a cylinder with a radius of 3 cm and a height of 7 cm.

Back

Surface Area = 2π(3)(7 + 3) = 2π(3)(10) = 60π cm².
