<u>Given</u>:
Given that the surface area of the cone is 54 square inches.
We need to determine the surface area of the cone that is similar to the cone three times large.
<u>Surface area of the similar cone:</u>
Let us determine the surface area of the similar cone.
The surface area of the similar cone can be determined by multiplying the surface area of the cone by 3. Because it is given that the similar cone is three times large.
Thus, we have;


Thus, the surface area of the similar cone is 162 square inches.
Its 160 .................
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>
