Formula of volume of hemisphere and sphere

The volume of a hemisphere of some radius can be easily found out by calculating just half of the volume of a sphere of the same radius. Volume of hemisphere = 2πr3/3, where r is the radius of the hemisphere

Step-by-step explanation:

Sphere volume = 4/3 πr³

Hemisphere volume = 2/3 πr³

Step-by-step explanation:

Above are the formulas for volume

Where r is radius  and π has value of 3.14

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
