Question 233463: The amount of metal S (in square inches) that it takes to make a can for tomato soup depends on the radius "r" and height "h":
S=2πr^2 +2πrh
a) rewrite the formula by factoring out the greatest common factor on the right hand side
b) Let h=5 in. and write a formula that expresses S in terms of r.

S=2πr^2 +2πrh
WHEN h=5:
S=6.28*r^2+6.28*r*5
S=6.28r^2+31.4r
S=6.28r(r+5) ans.
