Answer:
The surface area is approx. 1017.9 in^2.
Step-by-step explanation:
Total surface area of cone = πrl + πr^2. Since the radius is 12 in. and the slant height is 15 in, substitute 12 for r and 15 for l.
A = π(12)(15) + π(12)^2
= 180π + 144π
= 324π in^2
≈ 1017.9 in^2

Step-by-step explanation:
Answer:
(3,1)
Step-by-step explanation:
5y - 9 = 16
first isolate the y by adding 9 to both sides
5y - 9 (+9) = 16 (+9)
5y = 25
than divide 5 to completely isolate the y
5y/5= 25/5
Answer
y = 5
