Intro Surface Area and Review (p9)

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

How do you calculate the area of a circle?

Back

Area = πr², where r is the radius of the circle.

Front

What is the surface area of a cylinder?

Back

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

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

How do you find the area of a square?

Back

Area = side², where 'side' is the length of one side of the square.

Front

What is the relationship between radius and diameter?

Back

Diameter = 2 * radius.

Front

What is the surface area of a sphere?

Back

Surface Area = 4πr², where r is the radius.

Front

How do you find the area of a trapezoid?

Back

Area = 1/2 * (base1 + base2) * height.

Front

What is the formula for the area of a parallelogram?

Back

Area = base * height.

Front

If the radius of a circle is 4 cm, what is its area?

Back

Area = π(4)² = 50.24 cm².
