What is the diameter of a hemisphere with a volume of 2233\text{ cm}^3,2233 cm 3 , to the nearest tenth of a centimeter?

Agata [3.3K]

Answer:

The diameter of the hemisphere is 20.4 centimeters.

Step-by-step explanation:

The volume of an hemisphere is given by:

$V = \frac{2 \pi r^{3}}{3}$

In this problem, we have that:

$V = 2233$

$\frac{2 \pi r^{3}}{3} = 2233$

$2\pi r^{3} = 3*2233$

$r^{3} = \frac{3*2233}{2\pi}$

$r = \sqrt[3]{\frac{3*2233}{2\pi}}$

$r = 10.2$

The radius is 10.2 centimeters.

The diameter is double the radius. So:

2*10.2 = 20.4

The diameter of the hemisphere is 20.4 centimeters.

The rate to rent a small moving van is $30 per day, plus $0.25 per mile. The Sparkling Appliance Company rented a van because it

Zigmanuir [339]

Total rental cost = $390 = 2($30/day) + ($0.25/mile)x (x=number of miles)
330
Then 390 = 60 + 0.25x => 330 = 0.25 x => x = ------------
0.25

x comes out to 1320 miles.

How do I solve the multi step problem 8.5 - 1.2x = 6.7

LekaFEV [45]

First subtract 8.5 from both sides, then divide the -1.2 to get x by itself

x=1.5
