Answer:
-10x+2
Step-by-step explanation:
22-5(2x+4)
22-10x-20
2-10x
-10x+2
Take the root of both sides and solve.
c = - 7 sqr root 5
c = -1.258
ok you need formula for surface area.
SA = πrh+2πr^2
Plug in 25 and 5
SA = 2π(5)(25)+2π(5)^2
SA = 10pi*25 + 2pi(25)
SA = 250pi + 50pi
SA = 300pi
Hope this helps :)
