An ice sculpture in the form of a sphere is melting. Its spherical shape is maintained as the volume decreases at a constant rate of 

8π8 pi

 cubic meters per hour. At the moment the radius is 5 meters, what is the rate, in square meters per hour, at which the surface area of the sphere is decreasing? 

(Note: For a sphere of radius 

rr

, the surface area is 

A=4πr2cap A equals 4 pi r squared

 and the volume is 

V=43πr3cap V equals four-thirds pi r cubed

.)

1. Given 
   dVdt=-8πm3/hrthe fraction with numerator d cap V and denominator d t end-fraction equals negative 8 pi space m cubed / h r
    and we need to find 
   dAdtthe fraction with numerator d cap A and denominator d t end-fraction
    when 
   r=5mr equals 5 space m
   .
2. The volume and surface area formulas are 
   V=43πr3cap V equals four-thirds pi r cubed
    and 
   A=4πr2cap A equals 4 pi r squared
   .
3. Differentiate both formulas with respect to time (
   tt
   ) using the chain rule: 
   dVdt=4πr2drdtthe fraction with numerator d cap V and denominator d t end-fraction equals 4 pi r squared d r over d t end-fraction
    and 
   dAdt=8πrdrdtthe fraction with numerator d cap A and denominator d t end-fraction equals 8 pi r d r over d t end-fraction
   .
4. Substitute the given values into the differentiated volume equation to find 
   drdtd r over d t end-fraction
   : 
   -8π=4π(5)2drdtnegative 8 pi equals 4 pi open paren 5 close paren squared d r over d t end-fraction
   , which gives 
   drdt=−225m/hrd r over d t end-fraction equals negative 2 over 25 end-fraction space m / h r
   .
5. Substitute the values of 
   rr
    and 
   drdtd r over d t end-fraction
    into the differentiated surface area equation: 
   dAdt=8π(5)(−225)=−16π5m2/hrthe fraction with numerator d cap A and denominator d t end-fraction equals 8 pi open paren 5 close paren open paren negative 2 over 25 end-fraction close paren equals negative the fraction with numerator 16 pi and denominator 5 end-fraction space m squared / h r
   . 

Answer 

The surface area of the sphere is decreasing at a rate of 

16π5the fraction with numerator 16 pi and denominator 5 end-fraction

square meters per hour when the radius is 5 meters.
