The diameter of a sphere is 16 cm. What is the sphere's volume? Round to the nearest tenth.

ohaa [14]

Answer:

V ≈ 2144.70 $cm^3$

Step-by-step explanation:

Radius is going to be used instead of the diameter. Half of 16 is 8, and so that will be the value that shall be used.

$V = (4/3)\pi (8)^3$

V ≈ 2144.66 $cm^3$

V ≈ 2144.70 $cm^3$

Answer:

11 + x

Step-by-step explanation:

A = LW

W = $\frac{A}{L}$

Plug in given information:

W = $\frac{121-x^{2} }{11-x}$

Factor the numerator:

W = $\frac{(11+x)(11-x)}{(11-x)}$

Cancel (11 - x):

W = 11 + x
