Find the volume of the sphere. Give the answer in terms of pi and rounded to the nearest cubic foot.
Inessa05 [86]
Hi there!

The formula for the volume of a sphere is V = 4/3(pi)(r^3). Using this formula, we can plug in what we know and solve.

WORK:
V = 4/3(pi)(10^3)
V = 4/3(1000pi)
V = 4000pi/3 or 1333.3 pi
V also = 4188.8

Hope this helps!! :)

MatroZZZ [7]
The answer is 64 boys are in the soccer league.

X/160 = 40/100

X/160 * 100 = 40/100 * 100

5x/8 = 40

(8 * 5x)/8 = 40 * 8

5x = 320

5x/5 = 320/5

x = 64

stiks02 [169]
To determine the cost to fertilize the trees, you need to figure out how many kilograms of fertilizer are needed. With the information given, you can determine The number of grams needed to fertilize 1200 trees. To do this you would multiply 200 times 1200. This equals 240,000 grams. To convert this to kilograms, divide 240000g by 1000 g. Every group of 1000 g is 1 kg. The answer is 240 kilograms. Multiply 240 kg by the price of $2.75 per kilogram to get $660 as the cost.
