Find the value of x. round your answer to the nearest tenth.
a.) 52.6
b.) 52.9
c.) 6.2
d.) 6.5

Option A: 12.5

Step-by-step explanation:

We use trigonometric ratios on this right angled triangle.

we get:

Also cos 28° = 0.88

Therefore, x =

OPTION A is the answer.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
