Mathematics

Andrei [34K]3 years ago
4 0

Answer:

9 or 3.8x10^-6

Step-by-step explanation:

By flipping a coin you'd look at how many times a head could appear (1/2) and multiply that by the 18 times.

Another explanation:

I'm not sure on this but would you raise 1/2 to the 18th power?

What times what equals 120 and adds up to 14
sesenic [268]
No solution; 14/2 = 7; 7^2 = 49; 49 < 120
the 2 numbers that add up to 14 that would give the largest product is less than 120
maybe you mean 120 is negative?
idk i might be wrong

Find the surface area of a cylinder with a height of 7 m and a base radius of 5 m.
nekit [7.7K]

Answer: 376.8m

Step-by-step explanation:

Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14, h is the height= 7m and r is radius= 5m

rh = 5m x 7m = 35m while

r^2 = 5m x 5m = 25m

Slot the values into the formula:

V = 2 x 3.14 ( 35) + 2 x 3.14 (25)

V= (6.28 x 35) + (6.28 x 25)

= 219.8 + 157

V= 376.8m

I hope this helps.
