Answer:

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,

HIGH SCHOOL

What is the sum of the first 14 terms of the sequence -11+(-18)+(-25)+(-32)... -791

-483

-102

-714

The difference between -11 and -18 is -7

the difference between -18 and -25 is -7

the difference between -25 and -32 is -7

therefore we can say that the difference between all of the terms will be -7.

the first term is -11 -> call this a

the difference is -7 -> call this d

the number of terms is 14 -> call this n

use the equation (sum of) = (2a + (n-1)d)

(sum of) = (2 x -11 + (14-1)-7)

= -7(-22 + (13 x -7))

= -7(-22 + -91)

= -7(-111)

= 777

the difference between -18 and -25 is -7

the difference between -25 and -32 is -7

therefore we can say that the difference between all of the terms will be -7.

the first term is -11 -> call this a

the difference is -7 -> call this d

the number of terms is 14 -> call this n

use the equation (sum of) = (2a + (n-1)d)

(sum of) = (2 x -11 + (14-1)-7)

= -7(-22 + (13 x -7))

= -7(-22 + -91)

= -7(-111)

= 777
