Circles test: questions
Question 1 – Circumference [2 pts]
Find the circumference of the circle. Use \(\pi\approx\frac{22}{7}\).
Question 2 – Area [2 pts]
Find the area of the circle. Use \(\pi\approx 3.14\).
Question 3 – Find the radius [2 pts]
Question 4 – Leave it in pi [2 pts]
Question 5 – Semicircle [2 pts]
Find the perimeter and the area of the semicircle. Use \(\pi\approx 3.14\).
Question 6 – Wheel distance [2 pts]
Question 7 – Leftover metal [2 pts]
A circle of radius 10 in is cut from a 20-in square. Find the area of the leftover metal. Use \(\pi\approx 3.14\).
Question 8 – Track [3 pts]
- Find the distance around the track (two straight sides of 40 m and two semicircles of diameter 20 m). Use \(\pi\approx 3.14\). (1 point)
- Find the area enclosed. (1 point)
- A runner completes 5 laps. Find the distance run. (1 point)
Question 9 – Rug with a hole [3 pts]
- Find the area of the outer circle. (1 point)
- Find the area of the inner circle. (1 point)
- Find the area of the rug itself (the ring). Use \(\pi\approx 3.14\). (1 point)
Key facts behind this circles test
- Diameter \(d = 2r\); radius is half the diameter.
- Circumference \(C = \pi d = 2\pi r\).
- Area \(A = \pi r^2\) (square the radius first).
- \(\pi\) is about \(3.14\) or \(\frac{22}{7}\); leave answers in terms of pi to be exact.
- A semicircle has half the area of the circle; its perimeter adds the diameter.
How to use this circles test
Time yourself: the test is designed for an average student in 45 minutes. Answer the questions you are sure of first, then come back to the longer ones and check your units.
