Which expression can be used to find the volume of the sphere? diameter is 10 inches

8090 [49]

Answer:

$\large\boxed{V=\dfrac{4}{3}\pi R^3=\dfrac{D^3}{6}\pi}\\\\\boxed{V=\dfrac{500\pi}{3}\ in^3\approx523.33\ in^3}$

Step-by-step explanation:

$\text{The formula of a volume of a sphere:}\\\\V=\dfrac{4}{3}\pi R^3\\\\R-radius\\\\\text{A diameter}\ D=2R\Rightarrow R=\dfrac{D}{2}.\\\\\text{Therefore}\\\\V=\dfrac{4}{3}\pi\left(\dfrac{D}{2}\right)^3=\dfrac{4}{3}\pi\left(\dfrac{D^3}{8}\right)=\dfrac{D^3}{6}\pi$

$\text{We have the dimater}\ D=10in.\ \text{Substitute:}\\\\V=\dfrac{10^3}{6}\pi=\dfrac{1000}{6}\pi=\dfrac{500\pi}{3}\ in^3$

I'm not the greatest at math so I got stuck<br> x=<br><br> 80<br> 90<br> 100

sashaice [31]

The angle measure (120°) is the average of the measures of the two arcs (x, 2x). Hence
.. (x +2x)/2 = 120°
.. 3x = 240°
.. x = 80°

The difference between seven times a number and eight more than four times the number

Nookie1986 [14]

A difference is the result of a subtraction.

Call the number n.

"seven times a number": 7n

"eight more than four times the number": 4n + 8

"The difference between seven times a number and eight more than four times the number": 7n - (4n + 8)

Answer: 7n - (4n + 8)
