The area of the circle is expressed in the formula A = pi r^2 while the formula of getting the circumference of the circle is C = 2pi *r. Trying to express A in terms of C, we square C first into C2 = 4pi^2r^2. In this case, the answer to this problem therefore is A = C^2/4 pi. Answer is B
Answer:
8x
Step-by-step explanation:
thats not the answer
10 minutes is 1/6 of an hour.
1 hour and 10 minutes = 7/6 hours
98 km / 7/6 = 98 x 6/7 = (98 x 6) /7 = 588/7 = 84 km per hour
The formula for the area of a square is:
A=s²
Since we known that the area is 81ft², we can solve for the length of a side.
A=s²
81=s²
find the square root of both sides
9ft=s
The length of each side is 9ft
