The formula for the lateral area of a right cone la=pirs, where r is the radius of the base and s is the slant height of the cone. which are equivalent equations?

Answers

Answer 1
Answer:

Answer:

\pi r √(r^2+h^2)

Step-by-step explanation:

Given that there is a cone with radius r and slant height s.

We know that lateral surface area of the cone is

=\pi r s

Alternately if instead of s, h is known we can write this in terms of h also.

Consider the right triangle formed by slant height, height and radius of the cone.

Using Pythagorean theorem we have

s^2=r^2+h^2

Or s=√(r^2+h^2)

Hence lateral surface area of the cone

=\pi r √(r^2+h^2)

If the angles of a triangle are 10 45 and 23 what is the perimerter of the triangle

Answers

Answer:

No Solutions

Step-by-step explanation:

In a triangle, the sum of the angles has to be 180 degrees. It also is impossible to find the length of sides without at least one side, since the range of lengths is practically infinite. There are no solutions to this problem.

1)simplify the expression (2x)^4

2)the perimeter of a rectangular is twice the sum of its length and its width. the perimeter is 16 meters and its length is 2 meters more then twice its width

3)Find the real numbers x and y that make the equation true.

-3 + yi = x + 6i

Answers

(2x)^4=16x^4
------------------------------------------
2(l+w)=16\n l=2w+2\n\n 2(2w+2+w)=16\n 6w+4=16\n 6w=12\n w=2\n\n l=2\cdot2+2\n l=6
-------------------------------------------
-3+yi=x+6i\Rightarrow x=-3 \wedge y=6
