Circumference = 2(pi)(radius)
Circle 1: 48=2(pi)(radius)
24/pi = radius
Circle 2: 12 = 2(pi)(radius)
6/pi = radius
Area = (pi)(radius)^2
Circle 1: A = (pi) (24/pi)^2
= 576 / pi
Circle 2: A = (pi) (12/pi)^2
= 144 / pi
576/144 = 4 times greater
Answer:
d
Step-by-step explanation:
50 x 50 x 50 =125000, 3 sides = cubic feet
Answer: 43.96 feet
Step-by-step explanation:
C = 2πr or C = πd
Plug the numbers in: C = 3.14 * 14
3.14 * 14 = 43.96
Therefore, the circumference of the circle is 43.96 feet.
Answer:
x = 8.9 (nearest tenth)
Step-by-step explanation:
6^2 - 4^2 = 36 - 16 = 20
So
x = 2 * (√20)
x = 2 * 4.47
x = 8.94
It's an integer. The number can be written as a "top heavy" fraction but that is not a rational number. It is not an irrational number nor is it a natural number. Therefore it's an integer
