Answer:r = 2.81 centimeters
Step-by-step explanation:
The area of this circle can be found using the formula
A=πr^2
Where r = radius of the circle
π is a constant whose value is 3.14
We are given the area of the circle to be 25 square centimeters. To determine the length of the radius of the circle , we will make r the subject of the formula
r^2 = A/π
Taking square root of both sides of the equation,
r = √A/π
Since A = 25 and π = 3.14,
r= √25/3.14
r = 2.82166323992
Approximating to the nearest tenth of a centimeter,
r = 2.81 centimeters
Answer: All you have to do is divide 39 and 3 and you get 13. That is how many in a row.
Step-by-step explanation:
I hope that is right if not sorry.
Abigail collected more, she collected 87.5 lb
they collected 107.5 pounds together
It should be n+4=3n. Hope this helps
