PERT Geometry & Measurement Skills 3

Question 1

What is the area of a circle with a diameter of 10 m? (Use π ≈ 3.14)

Accepted Answer

78.5 m²

Answer

Radius = 5 m, so area = πr² = 3.14 × 25 = 78.5 m².

Question 2

Two angles of a triangle measure 50° and 60°. What is the third angle?

Accepted Answer

70°

Answer

The angles of a triangle sum to 180°, so 180° − 50° − 60° = 70°.

Question 3

A cylinder has a radius of 3 cm and a height of 10 cm. What is its volume? (Use π ≈ 3.14)

Accepted Answer

282.6 cm³

Answer

Volume = πr²h = 3.14 × 9 × 10 = 282.6 cm³.

Question 4

Convert 2,000 grams to kilograms.

Accepted Answer

2 kg

Answer

There are 1,000 grams in a kilogram, so 2,000 ÷ 1,000 = 2 kg.

Question 5

A right triangle has legs of 6 and 8. What is the length of the hypotenuse?

Accepted Answer

10

Answer

√(6² + 8²) = √100 = 10.
