Answer:
Step-by-step explanation:
a hemisphere is half a sphere.
And if the formula for the volume of a sphere is:
we must calculate the volume of the sphere and in the end divide by two to find the volume of the hemisphere.
Since the radius is:
substituting this into the formula for volume:
this is the volume of the total sphere, thus the volume of a hemisphere is:
rounding to the nearest tenth:
Divide total bought by 3 and multiply by 20cents:
210/3 = 70
70 x 0.20 = $14.00
Subtract the amount they paid by the amount they made:
14.00 - 6.50 = $7.50
The profit made was: $7.50

-4+9=5
Step-by-step explanation:
-2x-2x+5=-1-2x-2x+5=1
4 miles = 1 day
4miles divided by 1/3 distance on 2nd day = 1.33 miles ran on second day
4/1 x 1/3=4/3 4 divided by 3= 1.33 miles ran on the second day
If Will ran 1/3 of the distance that he ran on the first day (4 miles) the second day, he ran 1.33 miles
