Answer:
(9,20)
Step-by-step explanation:
9 and 20 together... (9,20)
let w = width and 3w = length
perimeter is the distance around the outside of the object or P = 2L + 2W
2(3w) + 2w = 24
6w + 2w= 24
8w = 24
w= 3
3w= 9
Width is 3in. and length is 9in.
Answer:

Step-by-step explanation:
Using exponential rules, this simplifies to
.
Volume of a cone:


r²h
Plug the radius and volume in the formula.


10²h = 942
Divide both sides by

.

10²h = 2,826
Divide both sides by pi.
10²h = 900
Divide both sides by 10² (100).
h = 9
The cone's height is 9 units.
