ECMS CIA 4 Review

Front

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

Back

Lateral Surface Area = 2πrh, where r is the radius and h is the height.

Front

What is the value of x if two angles are complementary, one angle is (2x+4) and the other is (3x+1)?

Back

x = 17

Front

How do you calculate the surface area of a rectangular prism?

Back

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

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines cross. They are always equal.

Front

What are complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

Calculate the lateral surface area of a cylinder with radius 7 cm and height 20 cm.

Back

Lateral Surface Area = 2π(7)(20) = 879.65 cm².

Front

What is the surface area of a rectangular prism with dimensions length = 10 m, height = 4 m, width = 3 m?

Back

Surface Area = 2(10*4 + 10*3 + 4*3) = 164 m².

Front

If angle 4 is 85 degrees, what is the angle complementary to it?

Back

The complementary angle is 5 degrees.

Front

What is the relationship between complementary angles?

Back

The sum of complementary angles is always 90 degrees.

Front

What is the formula for finding the area of a circle?

Back

Area = πr², where r is the radius.
