131.88 rounded is 132
Answer:
For the circle with the diameter of 7cm, the <u>area is about 38.48cm</u> and the <u>circumference is about 22cm</u>
For the circle with the diameter of 5cm, the <u>area is about 19.63cm</u> and the <u>circumference is about 15.7cm</u>
Step-by-step explanation:
The formula to find the area of a circle is pi*r^2
The formula to find the circumference is 2*pi*r
r = radius, which can be determined simply by taking the diameter, and dividing it by 2.
