The formula of cone's capacity is V = (1 / 3) (pi x r x h)
we know that r = 3.5, we must find h, the slant height is H=6.5, applying pythagorean theorem  h ^2 = H^2, so h= sqrt (H^2 -  r^2)
h =  sqrt (6.5^2 - 3.5^2) = 5.47
 finally, V = (1 / 3)  (3.14 x 3.5 x 5.47) = 20.03 cm^3
 the surface are is A = pi x r x H = 71.43 cm^2

{y=-x+1<br> {y=4x-14<br> please help me <br> my paper is due today
Temka [501]

- x + 1 = 4x - 14 \\  - x - 4x =  - 14 - 1 \\  - 5x =  - 15 \\ x = 3

Substitute x = 3 in any given equations. I will do in y = - x + 1

y =  - x + 1 \\ y =  - 3 + 1 \\ y =  - 2

Therefore the answer is (3,-2)
