Answer:
141 in³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes a cylinder, since the shapes of candles are cylindrical.
Given data
Radius r= 3in
Height h= 5in
Volume of cylinder V= πr²h
Substituting our given data we have
V= 3.14*3²*5
V= 3.14*9*5
V= 141.3in³
V= 141in³
Answer:
B. h=2A/(b1+b2) . . . . parentheses are needed
Step-by-step explanation:
Multiply the equation by the inverse of the coefficient of h. That coefficient is (b1 +b2)/2, so its inverse is 2/(b1 +b2). Parentheses are needed.
... 2A/(b1 +b2) = h
