The diameter of a sphere is 8 centimeters. What is the volume of the sphere? Use 3.14 for pi. Enter your answer, as a decimal, i

Angelina_Jolie [31]

The volume of a sphere is given by the equation $V= \frac{4}{3} \pi r^3$ , where r is the radius.

We are given the diameter of the sphere, but recall that the diameter is twice the radius: $d=2r$ . So the radius is half of the diameter: $r= \frac{1}{2}d$ .

Half of 8 cm is 4 cm.

We substitute this for r in the equation and we use 3.14 for <span>π.</span>

$V= \frac{4}{3}(3.14)(4)^3= \frac{(4^4)(3.14)}{3}=267.9 \ cm^3$

James took a total of 28 quizzes over the course of 4 weeks. How many

Andru [333]

Answer:

Step-by-step explanation:

We use rates to solve this so we do 28/4=7.

Using that, we know he can do 7 quizzes in 1 week.

Now 7 times 6= 42 right? so do 1 times 6.

The final answer is 6 weeks.

Hope this helps :)
