The volume of a cone is 35 ft^3 and the cone’s height is 7 ft. what is the area of the base of the cone?

area of base = 5 ft²

the volume (V) of a cone is calculated using the formula

V = Ah ( A is the area of base and h the height )

substitute given values into the formula

35 = 7A ( divide both sides by 7 )

A = = 5 ft²

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

b
