Answer: 37.64
Step-by-step explanation:
Given data:
Height of the cone = 4feet
Radius of the cone = 3feet
Therefore:
Perimeter of a cone = 1/3 * π * r*h
= 1/3 * 22/7 * 3² * 4
= 0.333 * 3.14 * 9 * 4
= 37.64 feet
The perimeter of the The cone and plane is 37.64feet
A diagram would be nice. If this is a right triangle, and one acute angle is 53 deg, then the other is 37 deg. You don't specify any dimensions, so all you can do is use theoretical values here.
If x is opposite the 53 deg angle, and the length of the hypotenuse is h, then side x has length h(sin 53 deg) = 0.799h.
The answer is b hope this helps god bless my friend
Angle of elevation is 37°
<u>Step-by-step explanation:</u>
As we have the opposite side 75 ft to the angle and the hypotenuse 125 ft, we can find the sine value as,
sin θ = opp/ hyp
= 75/125
= 0.6
θ = sin⁻¹ (0.6) = 36.9°≈ 37°
So angle of elevation is 37°.
