The formula for the volume, V, of a cone having the radius, r, and the height, h, is shown below. V = 3r2h
Write the formula to calculate the height, h.

V/3r²

Step-by-step explanation:

We are to make h the subject of the formula as shown;

V = 3r²h

Divide both sides by 3r²

V/3r² = 3r²h/3r²

V/3r²  = h

Rearrange

h = V/3r²

Hence the formula to calculate the height h is V/3r²

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
