NAEP Mathematics Grade 4

Question 1

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

Accepted Answer

282.6 cm³

Answer

Volume = π × r² × h = 3.14 × 9 × 10 = 282.6 cm³.

Question 2

If y = 2x + 3, what is the value of y when x = 5?

Accepted Answer

13

Answer

y = 2(5) + 3 = 10 + 3 = 13.

Question 3

A student scored 82, 90, 78, and 94 on four tests. What is the mean score?

Accepted Answer

84

Answer

(82 + 90 + 78 + 94) ÷ 4 = 344 ÷ 4 = 86.

Question 4

Which expression is equivalent to 4(3x − 2)?

Accepted Answer

12x − 8

Answer

Apply the distributive property: 4 × 3x − 4 × 2 = 12x − 8.

Question 5

On a coordinate plane, point A is at (2, 5) and point B is at (2, −3). What is the distance between them?

Accepted Answer

8

Answer

Since the x-coordinates are the same, distance = |5 − (−3)| = |8| = 8.
