Can you also write down the formula to solve it.
Answer:
1,072.33
Step-by-step explanation:
your formula π (pi) * r² * h
substitute r² for 8 and h for 16
the answer is 1,072.33
The value of r is 2 in the equation r+11+8r=29.
Two or more expressions with an Equal sign is called as Equation.
The given equation is r+11+8r=29
r plus eleven plus three times of r equal to twenty nine.
In the equation, r is the variable.
Add the like terms in the equation.
9r+11=29
Isolate the r term by subtracting 11 from both sides
9r=29-11
9r=18
Divide both sides by 9
r=2
Hence, the value of r is 2 in the equation r+11+8r=29.
