Answer:
<u>312π square inches</u>
Step-by-step explanation:
The surface area of a cylinder is the area of <u>both its bases and its lateral area added together. </u>
The area of a circle is <u>pi times the radius squared.</u> The radius in this case would be 6, half of the 12 inch diameter. 6 squared is 36, making one base 36π inches squared. Multiply that by two to get the area of both bases; 73π inches squared.
The lateral area of a cylinder is the <u>circumference of the base multiplied by the height of the cylinder. </u>Circumference being <u>pi times the diameter,</u> it would be equal to 12π. Multiply that by the height to get 240π.
Then <u>add the two values together</u> to get 312π, the final answer.
Answer:
2
Step-by-step explanation:
|x| means absolute value
|x| means if x is positive or negative, its still positive
-5|x|+4=14
-5|x|=10
|x|= -2
answer is 2

Answer:
y=19
Step-by-step explanation:
3(y - 9) = 30
3y - 27 = 30
3y = 30 + 27
3y = 57
y = 19
