Acylinder has a diameter of 40 feet and a height of 32 feet. what is the surface area of the cylinder? express the answer in terms of

Step-by-step explanation:

Since, the surface area of a cylinder is,

Where, r is radius,

h is the height,

Here,

The diameter of the cylinder = 40 ft,

So, the radius of the cylinder, r =

And, h = 32 ft

Thus, the surface area of the cylinder is,

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
