(x+5)(x-5) , You use difference of two squares to do this. Remember that if the sign in the equation was (+) then you wouldn’t be able to continue factoring. You can only factor equations like these if there is a subtraction sign.
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
Answer: 2/5
