Question

What is the volume of a sphere with a surface area of 64 cm??

Answer 1

Explanation:

Parallel lines r and s are cut by two transversals, parallel lines t and u.

Lines r and s are crossed by lines t and u to form 16 angles. Clockwise from top left, at the intersection of r and t, the angles are 1, 2, 3, 4; at the intersection of s and t, 5, 6, 7, 8; at the intersection of u and s, 9, 10, 11, 12; at the intersection of u and r, 13, 14, 15, 16.

Which angles are alternate exterior angles with angle 11?

Angle5 and Angle13

Angle7 and Angle15

Angle6 and Angle16

Angle8 and Angle14

Answer 2

V = 163.58 cm^3

Explanation:

V=
`A^(3/2)`

`\6{6√(\pi ) }`

where V = volume and A = Surface area

Surface area = 64

V = 64^3/2

6
`√(22.7)`

V =
`(√(64) )^(3) /` 6 X 1.77

V= 8^3 / 3.13

V = 512/3.13

V = 163.58 cm^3
