<h3>Given:-</h3>
- radius = 7 inches
- height = 9 inches
<h3>To find:</h3>
we know:-
So:-
⇢SA of cylinder=2πrh+2πr²
⇢SA of cylinder = 2πr(h+r)
⇢SA of cylinder = 2 × π × 7(7 + 9)
⇢SA of cylinder = 2 × π × 7 (16)
⇢SA of cylinder = 2 × π × 112
⇢SA of cylinder = 2 × 112 × π
⇢SA of cylinder = 224π inches ²
.°. <u>Surface</u><u> </u><u>Area</u><u> </u><u>of</u><u> </u><u>cylinder</u><u> </u><u>is</u><u> </u><u>224π inches</u><u>²</u><u>.</u>
To find scale factor you first must find two corresponding sides. then divide one by the other. note that if you divide the smaller side by the larger you will get a number less that one and if you divide the larger side by the smaller side you will get a number greater than one.
The 3rd one cause at first its 1ft = 10ft and it was an 8 by 8 square and now its a 4 by 4 square meaning it was divided by 2 meaning you divide 10 by 2 getting 1ft = 5ft
