Perimeter = (length+width) x 2

Let w units be the width of the rectangle.

Length of the rectangle = 2w

Perimeter:
(2w+w) x 2 = 60

(3w)2 = 60

6w = 60

w = 10

Area:
2(10) x 10

= 20 x 10

= 200 units

The main show tank has a radius of 60 feet and forms a quarter-sphere. what is the volume of the quarter-sphere shaped tank? rou

schepotkina [342]

By definition, the volume of a quarter of a sphere is given by:
$V = (1/4) * (4/3) * (\pi) * (r ^ 3)
$
Where,
r: sphere radius
Substituting values we have:
$V = (1/4) * (4/3) * (3.14) * (60 ^ 3)
$
Making the corresponding calculation we have:
$V = 226080 feet ^ 3$
Answer:
The volume of the quarter-sphere shaped tank is:
$V = 226080 feet ^ 3$
