Question

Can somebody help me w/ this math problem?
ok it wouldnt copy the sphere so u jus have to work with this. the spheres radis is 1/2 in

7. Find the volume of the following figure using the appropriate formula. Use 22 7 ⁢     for ⁢       π .

Sphere: V = 4 3 πr 3




A. 44 21 in 3
B. 88 21 in 3
C. 11 21 in 3
D. 22 21 in 3

Answer 1

V = (4/3)(pi)(r^3)
= (4/3)(22/7)(1/2)^3
= (4/3)(22/7)(1/8)
= 11 / 21

Answer 2

Volumf of a sphere vormula

V = 4/3 π r³

V = 4/3(22/7)(1/2)³

V = 4/3(22/7)(1/8)

V = 4/3(22/56)

V = 88/168

V = 11/12 in³

Answer 3

v=4/3 pir^3=4/3x22/7x1/8=0.524in^3
