Which statements are true? Check all that apply. The radius of the cone is 9 units. The height of the cone is 15 units. The height of the cone is 12 units. The volume of the cone is represented by the expression One-thirdπ(15)2(9). The volume of the cone is represented by the expression One-thirdπ(9)2(12).

Statements 1,3,5 are true! .

Step-by-step explanation:

Here we have , Following statements to check :

Here , We have following parameters:

Also , We know that volume of cone =

⇒

So , With above discussion it's clear that , Statements 1,3,5 are true! .

A, C, E

Step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

what level of math? also i don't need to be paid if i can you.
