Answer:
1) Radius of the cone = 9.5 cm
2) BA = 90.25 π cm²
3) SA = 384.7 π cm²
Step-by-step explanation:
1) Radius of the cone = 9.5 cm
2) Base Area of the cone = 
BA = (π)(9.5)²
BA = 90.25 π cm²
3) Surface Area of Cone = 
SA = π(9.5)(9.5 + √(29.5)²+(9.5)²)
SA = 9.5π(9.5 + 31)
SA = 9.5π(40.5)
SA = 384.7 π cm²

Answer:
The student ticket is 200 and the adults is 550
Step-by-step explanation:
So the set up is :
750 = x + y
5300 = 8x + 4.5 y
x will be adults and y will be students
Assuming you don't have calculator then you want to be able to eliminate either x or y from this system. The easiest is X cause its a whole number.
So multiply all the numbers from the first equation by 8 which gives
6000 = 8x + 8 y
5300 = 8x + 4.5 y
Then subtract the numbers (6000-5300 and 8x-8x and 8y-4.5y)
which gives :
700 = 3.5y
Solve for y = 200
and plug 200 back into any equation to solve for X
750 = x + 200
x = 550
