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.
Is there some sort of paper that shows you what to do?
Well, 3^9 is the same thing as
3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
So 3^9 is equal to 19,683
Answer:
<h3>The length of y is 62.82 cm.</h3>
Step-by-step explanation:
We are given a right triangle with an angle 30°.
Opposite side of angle 30° is x and adjacent side is y.
Also, given length of side x=36.25 cm.
In order to find the value of y, we need to apply tangent trigonometrical ratio.
We know,
Therefore,
Plugging values of and x=36.25, we get
Plugging value of in above equation, we get
On multiplying both sides by y, we get
0.577y=36.25
Dividing both sides by 0.577, we get
y=62.82
<h3>Therefore, the length of y is 62.82 cm.</h3>
