Abarrel filled with oil is a cylinder with a diameter of 22 inches and a height of 33.5 inches. there are 231 cubic inches in a liquid gallon. to the nearest gallon, how many gallons of oil does the barrel hold?
a) 50 gallons
b) 52 gallons
c) 55 gallons
d) 58 gallons

C. 55 gallons because the formula for cylinder volume is V=pi•radius^2•height. So plug in the given values like in the pic below and then divide that by 231 to find the gallons

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
