Answer:
=50.29
Step-by-step explanation:
The perimeter of a circle is also called the circumference
C = 2 * pi *r
25 1/7 = 2 * 22/7 *r
Rewriting as an improper fraction on the left
(25*7 +1)/7 = 44/7 *r
176/7 = 44/7 r
Multiplying each side by 7/44
7/44 *176/7 = 7/44 *44/7 r
4 = r
We can now find the area by
A = pi r^2
A = (22/7) * 4^2
A = 22/7 * 16
=352/7
Rounding to the nearest hundredth
=50.29

Answer:
50
Step-by-step explanation:
Let the numbers be 3x, 4x, 5x
(3x)^3 + (4x)^3 + (5x)^3 = 216000
27x^3 + 64x^3 + 125x^3 = 216000
216x^3 = 216000
x^3 = 1000
x = 10
5x = 5(10) = 50
