1) its number 2. 30x^7y^4
What is the intrist rate ? kind of need that to answer
Volume of the cone: 1/3 of area of the circle * the height
(1/3)π5²*5=(125/3)π
volume of the cylinder: area of the circle *the height: π5²*10=250π
add up: (125/3)π+(125/3)π+250π≈1047.2
D is the correct answer
I am pretty sure that the answer is 15+ n or it could be 15n
