Find the perimiter of this shape
juin [17]

Answer:

The perimeter of the shape is (7x²+10x+81) inches.

Step-by-step explanation:

When finding the perimeter of a shape, you have to add up all the side lengths :

p = 31 + (4 {x}^{2}  + 8x) + (3 {x}^{2}  - 5x + 20) + (7x + 30)

p = 31 + 4 {x}^{2}  + 8x + 3 {x}^{2} - 5x + 20 + 7x + 30

p =( 7 {x}^{2}  + 10x + 81) \: inches

Gnom [1K]
Aiden should have calculated 
area = (1.1 * 5.4) / 2
because triangle area = half the base times the altitude.

if you use the formula on how to find the volume of a cone

V=\pir^2*h/3

you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900\pi ft^3
