The large sphere has a diameter of 20 feet.
Which expression represents the volume, in cubic units, of
the shaded part of the sphere?
-4ft
37(109) + 37(4)
7(109) – 2014)
1(209) + (4)
7(209) – 17(43)

Step-by-step explanation:

The volume of a spherer is defined as

Where is the radius and

According to the proble, the diameter is 20 feet. By definition of radius,

Replacing the radius in the volume formula

Therefore, the volume of the sphere is 4187 cubic feet, approximately.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
