Use the net below to determine the surface area of the cylinder. (Use 3.14 for Tr.)
baherus [9]

Option D:

Surface area of the cylinder = 753.6 cm²

Solution:

<u>To find the surface area of the cylinder:</u>

Given data:

Radius of the cylinder = 6 cm

Height of the cylinder = 14 cm

The value of π = 3.14

Surface area of the cylinder = 2 \pi r^{2}+2 \pi r h

                                              =2\times 3.14\times6^2+2\times3.14\times 6 \times14

                                              = 226.08 + 527.52

                                              = 753.6 cm²

Surface area of the cylinder = 753.6 cm²

Darnelle drew this figure and the accompanying equations.
kondor19780726 [428]

Answer:

Option D. w + x = z

Step-by-step explanation:

see the attached figure to better understand the problem

we have

w+x+y=180 ----> equation A

y+z=180 ----> equation B

equate equation A and equation B

w+x+y=y+z

Subtract y both sides

w+x=z

This equation satisfy the <em><u>Triangle Exterior Angle Theorem</u></em> (An exterior angle of a triangle is equal to the sum of the opposite interior angles)

Sunny_sXe [5.5K]

Step-by-step explanation:

In order to remove the requirement for change, every time the client buys a product for $0.20 the random number that lies between 0 and 1 would be produced also the same would be rounded to the closest value i.e. 0 or 1. In the case when 0 arise so the customer would not have to pay any amount but if 1 arise so the customer have to pay $1. So this type of method would remove the requirement for a minor change
