Which equation gives the volume of the sphere? O V=2/3(27ń)
O V=4/3(27)
O V= 2/3 (27)
O V= 4/3 (27ń)

The correct option is (b).

Step-by-step explanation:

A sphere and a cylinder have the same radius and height,

The volume of cylinder is,

ATQ,

The volume of cylinder is 27 cubic units.

The formula for the volume of a sphere is given by :

So, the correct option is (b).

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
