Answer:
x = (-12/7 , 0)
y= (0,4)
Step-by-step explanation:
Plug y=0 into the equation and solve the resulting equation 7x=−12 for x
7x = -12
/7 /7
x = -12/7 and y =0
Plug x=0 into the equation and solve the resulting equation −3y=−12 for y
-3y = -12
/-3 -3
Y = 4 and X = 0

Answer:
1306.24 cm².
Step-by-step explanation:
From the diagram given above, we obtained the following information:
Radius (r) = 13 cm
Pi (π) = 3.14
Slant height (l) = 19 cm
Surface Area (SA) =.?
The surface area of the cone can be obtained as follow:
SA = πr² + πrl
SA = πr ( r + l)
SA = 3.14 × 13 ( 13 + 19)
SA = 40.82 (32)
SA= 1306.24 cm²
Therefore, the surface area of the cone is 1306.24 cm².
