Answer:
176.89in^3
Step-by-step explanation:
when finding the volume using the surface area, the best method that comes in my mind is finding the ratio between the surface area and volume which would be r/3 for a sphere. So if given that the surface area of the sphere is 152.39 square r/3=around 1.161, and when multiplied by 152.39 is around 176.89. another similar method is deriving the radius when given its surface area which is simply taking the square root of the surface area/4pi which turns out to be 3.482357088 or 3.48 which can then be plugged into the volume formula as the radius which is (3.48^3*4pi)/3 which turns out to be the same answer!

Answer:
x=3
Step-by-step explanation:
25x+57+x=45x
26x+57=45x

x=57/19
x=3
Answer:
Maggie's age is 13 years
Step-by-step explanation:
Let
x ------> Maggie's brother age
y ------> Maggie's age
we know that
x+y=43 ------ > equation A
x=3y-9 ------> equation B
substitute equation B in equation A and solve for y
(3y-9)+y=43
4y=43+9
4y=52
y=13
therefore
Maggie's age is 13 years
