Jayden is correct. the pythagorean theorem states that a^2+b^2=c^2 so jayden’s work would make the most sense by plugging in what we already know into a and b and then solving for c.

i hope this helps and sorry if i’m wrong

The surface area of a cone is 54 square inches. What is the surface area of a similar cone that is three times as large?

12345 [234]

Given:

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.

Surface area of the similar cone:

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;

$SA = 3 \times 54$

$SA=162$

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

Solve the equation: sin(2x)= sin x

Anna [14]

Answer:

Below

Step-by-step explanation:

sin(2x) = 2 ×cos(x)× sin(x)

● sin(x) = 2 × cos(x) × sin(x)

● 2 × cos(x) = 1

● cos (x) = 1/2

So we can deduce that:

● x = Pi/3 + 2*k*Pi

● or x = -Pi/3 + 2*k*Pi

K is an integer

slant height of a right cone is 5 inches, and radius of its base is 3 inches, what is the lateral area?

Alik [6]

*Hint: The formula for the lateral surface area of a right cone is LA= Πrs

All we have to do is plug in and solve.

LA= Π(3)(5)
LA = 15Π
LA = 47.1238898

The lateral surface area is around 48 inches.
