A tree trunk is approximated by a circular cylinder of height 100 meters and diameter 4 meters. The tree is growing taller at a rate of 2 meters per year and the diameter is increasing at a rate of 5 cm per year. The density of the wood is 2000 Kg per cubic meter. How quickly is the mass of the tree increasing?

Step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
