If the sphere shown above has a radius of 4 units, then what is the approximate volume of the sphere? A.
334.93 cubic units
B.
21.33 cubic units
C.
100.48 cubic units
D.
267.95 cubic units

Answers

Answer 1
Answer: Volume of the Sphere is D. 267.95 cubic units

Volume of a sphere can be found by multiplying the fraction of 4/3 to the Pi and the cube of the radius.

V = 4/3 * π * r³            where r = 4 units ; π = 3.14

V = 4/3 * 3.14 * 4³
V = 4/3 * 3.14 * 64
V = 4/3 * 200.96
V = 267.95 cubic units

Seven times the sum of a number and 2 is equal to 9

Answers

Let x = a number

7(x + 2) = 9

Then we solve for x. First, distribute:

7x + 14 = 9

Subtract 14 from both sides:

7x = -5

Divide by 7 on both sides:

x= (-5)/(7)

The number is then -5/7.

120 meals to 52 meals. Find the percent of change. Round to the nearest tenth of a percent if necessary.

Answers

If you would like to find the percent of change, you can calculate this using the following steps:

x% of 120 meals is 52 meals
x% * 120 = 52
x/100 * 120 = 52
x = 52 * 100 / 120
x = 43.3%

100% - 43.3% = 56.7%

The percent of change is 56.7%.

One serving of this cereal provides you with 160 mg of sodium. This is 7% of your body's daily needs. How many milligrams of sodium equal 100%?

Answers

First, we see the closest multiple of 7 under 100 is 98 and that divided by 7 is 14. there are 2/7 as our remainder. We do 2/7 times 160 to get 320/7 and 320/7 = 45 and 5/7. We convert 5/7 into a decimal like 5/7 = .7. The answer is 45.7 milligrams of sodium.
