The surface area of a cylinder is the sum of the surface areas of the bases (2 circles) and the side of the cylinder (a rectangle).
The area of the bases is 2 times the area of each base, and each base is a circle,
The area of the side is a rectangle that has as length, the circumference of the base, and as width, the height of the cylinder.
diameter = 2; radius = diameter/2 = 2/2 = 1
height = 16
30 mph would be a safe speed for you to drive.
Collisions are much more likely to occur when one driver travels greater speedy or more slowly than the alternative motors on the road. You have to input a throughway at or near the velocity of visitors except if the speed of site visitors exceeds the prison speed restrict.
A pedestrian has a 90 percent threat of survival if hit by a vehicle transferring at 30 km ph (18.64 mph). This decreases to 70 percent at 40 kmph (24. eighty five mph) and much less than 20 percent at 50kmph (31 mph). driving at decreased speeds also enables drivers to stop within a shorter distance.
Retaining high speeds on highways is straightforward, as roads are wider and traffic is usually mild. If there are signs that show a pace restriction of 80kph, use them as a guide and stick near them. it's also an excellent exercise to assess road situations and set your pace thus.

Answer:
21 mails
Step-by-step explanation:
Let there are x no of texts and y no of emails.
Condition 1,
x+y = 20 ...(1)
Condition,
x=2y-1 ...(2)
Put the value of x from equation (2) in (1). So,
(2y-1)+y = 20
Taking like terms together,
2y-y=20+1
y=21
So, Devin sent 21 mails,.
$7.87+$46.32=$54.19. If you multiply 46.32 by 0.17, 17%, it is 7.87 so you just add that to the original bill, 46.32
