Please help me with this. U can just go like 1. Yes or no 2.Yes or no (etc) Thanks !!

Step-by-step explanation:

Radius Height Yes/No

Sphere 4cm 8cm No

Cone 8cm 5cm Yes

Sphere 4.5cm 9cm Yes

Cone 9cm 3cm Yes

To find height of sphere: 2 x r

2 x 4 = 8

2 x 4.5 = 9

Volume of a Sphere = 4/3 x π x r^3

Volume of a Cone = π x r^2 x h^3

4/3 x π x 4^3 = 268.082 = 268cm^3

π x 8^2 x 5^3 = 25132.741 = 25133cm^3

4/3 x π x 4.5^3 = 381.703 = 382cm^3

π x 9^2 x 3^3 = 6870.663 = 6871cm^3

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
