- 1.A circular garden has a radius of 7 meters. Calculate the circumference and the area of the garden. Use π ≈ 2 2/7.
- 2.A rectangular prism has a length of 8 cm, a width of 5 cm, and a height of 12 cm. Calculate the total surface area and the volume of the prism.
- 3.In the diagram below, line AB is parallel to line CD. Line EF is a transversal. If angle 1 measures 115 degrees, find the measures of angles 2, 3, and 4. (Assume a diagram where angle 1 is upper left of intersection AB/EF, angle 2 is upper right, angle 3 is lower right, angle 4 is lower left of intersection AB/EF. Angle 3 and angle 1 are vertically opposite, angle 2 and angle 4 are vertically opposite. Angle 1 and angle 2 are supplementary. Angle 1 and angle 3 are consecutive interior angles with angle 5 on line CD).
- 4.Sarah wants to buy a new laptop that costs 1200. She has saved 500 and can get a loan for the rest. The loan has an annual interest rate of 8%. If she pays back the loan in one year, how much interest will she have to pay?
- 5.A regular hexagon has a side length of 6 inches. Calculate the perimeter and the area of the hexagon. (Hint: A regular hexagon can be divided into 6 equilateral triangles).
- 6.A company is designing a cylindrical can for soup. The can needs to have a volume of 1570 cubic centimeters. If the radius of the can is 5 cm, what should be the height of the can? Use π ≈ 3.14.

How often should my child practice geometry & measurement?
Short daily practice sessions of 10-15 minutes are more effective than long weekly sessions. Consistency builds lasting understanding.
How do I know if my child is at the right level for these worksheets?
If your child can complete about 70% of the problems correctly, the level is appropriate. If it's too easy or too hard, try an adjacent grade level.
Can I use these worksheets for homeschool?
Yes. The worksheets align with standard curriculum expectations and can supplement any math program. Generate multiple worksheets to create a full practice set.
