If r=12 units and h=8 units, what is the volume of the cylinder shown above? use 3.14 for (pi)

V= 3617.28 cube units

Step-by-step explanation:

Volume of cylinder given as , V = πr²h

Where, r = radius of cylinder  , h = height of cylinder

Given,

r = 12 units  and h = 8 units

Plug these values into the formula of volume for cylinder.

V = πr²h = 3.14 * (12)² * 8    (Since r= 12 and h = 8)

V = 3.14 * 144 * 8  = 3617.28 cube units

hence we get volume of cylinder as 3617.28 cube units

(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
