What is the area of the shaded region?

Use 3.14 for ​ π ​.

Enter your answer as a decimal in the box.


cm²



The area of a rectangle with dimensions of 8 cm by 6 cm is removed from the area of a circle with a radius of 5 cm.

Answer 1

Answer: 30.5 cm².

I just took the test and plus it makes sense

Answer 2

Answer: 30.5 cm²

To get the the area of the rectangle all we have to do is:

Rectangle Area = 6 × 8 = 48 cm²

Same thing to the circle, multiply the radius and pi:

Circle Area = 3.14 x 5² = 78.5 cm²

We have to subtract the two areas to find the shaded area.

78.5 - 48 = 30.5 cm²

I hope this helps!
