Answer:
Step-by-step explanation:
the formula for calculating the perimeter of a circle (the circumference C) is:
2π * r
And the area is:
π * r²
r is the radius.
Radius is the half of the diameter. The diameter here is equal to two square. One square is 5 of side.
The diameter is 10 and the radius is 5
<h3>C = 2 * 3.14 * <u>5</u> = 31.4</h3><h3>A = 3.14 * <u>5²</u> = 3.14 * 25 = 78.5</h3>
It is the same for the other circle
Answer:
20$
Step-by-step explanation:
A quarter is 0.25 cents so if you have 84 all you gotta do is multiply 84 x 0.25 and the answer is just 21$ so the closest answer is 20$ unless you can add the 20$ with the 1$ bill to get the final answer.
