Which equation can be used to find the surface area of the cylinder?

r = 4 in.

h = 16 in.

S-2314) + 2(4x(16)

S=2x{8)2 + 2x{816)

S-23/16) + 2(16)(4)

S-214) + 2(9116)

S = 2π(16) + 2π(4)(16)

        or

S = 2(3.14)(16) + 2(3.14)(4)(16)

Step-by-step explanation:

The surface area of a cylinder is the sum of the area of it bases and the lateral face. A cylinder has 2 circular base .

The surface area = area of 2 circular base + lateral face area

surface area = 2πr² + 2πrh

surface area = 2πr(r + h)

The surface area equation for a cylinder that has a radius as 4 inches and h as 16 inches can be represented using the formula below.

surface area =  2πr² + 2πrh

where

r = radius

h = height

r = 4 inches

h = 16 inches

S  = 2π(4²) + 2π(4)(16)

S = 2π(16) + 2π(4)(16)

Assuming π was given as 3.14 the equation will be as follow

S = 2(3.14)(16) + 2(3.14)(4)(16)

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
