Question 1

What type of angle is 135°?

Accepted Answer

Obtuse

Answer

An obtuse angle measures between 90° and 180°, so 135° is obtuse.

Question 2

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

Question 3

How many lines of symmetry does a regular hexagon have?

Accepted Answer

6

Answer

A regular hexagon has 6 lines of symmetry — one through each pair of opposite vertices and one through each pair of opposite edge midpoints.

Question 4

Accepted Answer

2,500 m

Answer

1 km = 1,000 m, so 2.5 km = 2,500 m.

Question 5

A path goes 3 miles north, then 4 miles east. How far is the endpoint from the start in a straight line?
