If the surface area of a sphere is 484π, what is the radius?
2 answers:
Answer:
It would be 11.
Step-by-step explanation:
The equation for the surface area of a sphere is 4πr^2, so lets reduce the answer to get the value of r, the radius.
484π = 4πr^2
Divide by π
484 = 4r^2
Divide by 4
121 = r^2
Lastly, square root each side
11 = r
r is 11.
Answer:
6.21 is the radius I believe

x = 4.56
Step-by-step explanation:
57 + x + 25x + x = 180
27x + 57 = 180
27x = 123
x = 4.56

To figure it out, cross multiply:
32=21
Since the values are not equal, 2/3 does no equal 7/16
9 is the value of each side. There are 7 sides so 63 divided by 7 is 9.
