The diameter of a sphere is 10 in. What is the sphere's volume? Round to the nearest tenth, if necessary. A) 104.7 in3 B) 209.4
denis23 [38]
To find the volume of a sphere, you will use the formula for finding volume of a sphere. You will use the diameter to find the radius.  r = d/2, so the radius is 5 in

V = 4/3 x pi x r^3
      4/3 x 3.14 x 5^3
V = 523.6 cubic inches

The volume of this sphere is approximately 523.6 cubic inches.

Simplify 5(5t+6)+2 (2t-3)
yan [13]

Answer:

29t + 24

Step-by-step explanation:

5(5t + 6) + 2(2t - 3)

Open Parentheses first.

5* 5t = 25t

5 * 6 = 30

25t + 30 + 2(2t - 3)

Open others

2 * 2t = 4t

2 * 3 = 6

25t + 30 + 4t - 6

Match like terms

29t + 24
