Answer:
1436.76 in.^3
Step-by-step explanation:
This question means to find the volume of a sphere with a diameter of 14 inches. The formula for the volume of a sphere is 4/3πr^3, so we need to find the radius, which is half the diameter. Half of the diameter is 7 inches, so now we can plug in our values to find the volume is about 1436.76 cubic inches.

Answer:
36 boys
Step-by-step explanation:
let x be the number of pupils in the class , then
x + 24 = x ( multiply through by 5 to clear the fraction )
3x + 120 = 5x ( subtract 3x from both sides )
120 = 2x ( divide both sides by 2 )
60 = x
Then
number of boys = × 60 = 3 × 12 = 36
140 total members. 35 is just 1/4 of the members there so you can just multiply it 4 times to get your answer because 100% of members is 140
35 = 25%
70 = 50%
105 = 75%
140 = 100%
