Ahemisphere has a diameter of 45 centimeters. a larger hemisphere has a diameter of 57 centimeters. what is the surface area to volume ratio of the smaller hemisphere? round to the nearest hundredth.

We know that
[surface area of hemisphere]=2*pi*r²
[volume of hemisphere]=(4/6)*pi*r³

so
[surface area to volume ratio of hemisphere]=(2*pi*r²)/((4/6)*pi*r³)
[surface area to volume ratio of hemisphere]=3/r

for the the smaller hemisphere
diameter=45 cm
r=45/2> r=22.5 cm
[surface area to volume ratio of smaller hemisphere]=3/22.5> 0.13

the answer is
0.13

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
