Which of the following equations could be solved for a radius? select all that apply.

!

A = π · (r²)

Step-by-step explanation:

π · r² is the area of a circle.

While π · r² · h can also give you the radius, it can only do so for the Volume , not the Area .

doesn't really apply for a circular object, as it requires the length and width. For circular objects, both are equal to the diameter of the object, and 2² · r² · h does not equal the Volume.

π · r³ seems awfully like the volume of a sphere, but there's something missing. The true volume of a sphere is · π · r³, not π · r³.

only applies for triangles.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
