At constant acceleration the equation is
v = u + at where u = initial speed, a = acceleration. t = time and v = final speed
So here we have 18 = 0 + 7t
t = 18/7 = 2.6 seconds ( to nearest tenth)
Answer:
320cm.²
Step-by-step explanation:
= 5
2 + 2[5] = 96 ↷
2 + 10 = 96 ↷
12 = 96 ↷
= 8 [plug this back into the top equation to get 40 units]
[8][40] = 320 [Area]

Answer:
A = 533.8 square inches
Step-by-step explanation:
Use the surface area of a cylinder formula (A=2πrh+2πr^2)
Plug in 12 for h and 5 for r
Use 3.14 in replace for π
A = 2(3.14)(5)(12) + 2(3.14)(5)^2
A = 533.8 in^2
