The slope is 2
the y-intercept is at (0, 7)

The correct answer is letter
C. 868.30 cm^2 (centimeter squared)
See attached figure for reference of the two cones.
Solution:
Find first the radius.
To find the radius we must multiply 13.8 to 4.6 and multiply it by 3.7
Thus,
(13.8 / 4.6) x 3.7 = 11.1
To find the surface area of the larger cone we use this formula:
((pi x rad x slide length) + (pi x rad^2))
Where:
rad or radius = 11.1
slide length = 13.8
((pi x 11.1 x 13.8) + (pi x 11.1^2)) =
868.30 cm^2

For a vector:
cos^2(α) + cos^2(β) + cos^2(γ) = 1
From the givens:
α = π/4, therefore, cos(α) = 1/root 2 and cos^2(<span>α) = 1/2
</span>β = π/3, therefore, cos(β) = 1/2 and cos^2(<span>β) = 1/4
Substitute in the above equation:
1/2 + 1/4 + </span>cos^2(γ) = 1
cos^2(γ) = 1 - 1/2 - 1/4
cos^2(γ) = 1/4
cos(γ) is either 1/2 or -1/2
For cos(γ)= 1/2 .......> γ = <span>π/3
For </span>cos(γ)= -1/2 .......> γ = 2π/3
