15. It is 50.20

because the formula is r²*3.14 and the radius if half of the diameter and the diameter is 8 and half of it would be 4 and 4²=16 so 16*3.14= 50.24

What value of z makes the statement true?
Shkiper50 [21]
-(z + (-17)) = 12 + 17

-(z - 17) = 12 + 17

Distribute -1:

-z + 17 = 12 + 17

Subtract 17 to both sides:

-z = 12

Multiply -1 to both sides:

z = -12

If you doubled the radius of a sphere, how would the volume change? A. The volume would double. B. The volume would triple. C. T
Ronch [10]
The volume of a sphere, V = (4/3)(PI)(R^3) Let k = (4/3)(PI) Therefore, V = k (R^3) Let R’ = new radius = 2R V’ =k (R’^3) = k (2R)^3 = 8 k R^3 = 8 V The volume would be eight time the original volume.

1) There are 80 grams of salt in a 32% solution. Find the weight of the solution
alukav5142 [94]

Answer:

Weight of the solution = 250 grams

Step-by-step explanation:

1) Consider the weight of solution as x grams.

32 % solution = 80 grams salt

32% of x = 80

(32/100)*x = 80

Solving for x:

x  = (80*100) / 32

x = 250 grams
