Answer:
Surface are of cylinder having height 9 mm and radius 7 mm is 703.36 mm²
Step-by-step explanation:
We are given:
Height of cylinder = 9 mm
Radius of cylinder = 7 mm
We need to find surface area of cylinder.
The formula used to find surface area of cylinder is: [tex]\mathbf{Surface \ Area \ of \ cylinder = 2\pi rh+2\pi r^2}[/tex]
Now, putting values and finding surface area of cylinder
[tex]Surface \ Area \ of \ cylinder = 2\pi rh+2\pi r^2}\\Surface \ Area \ of \ cylinder = 2\times 3.14 \times 7 \times 9+2\times 3.14 \times (7)^2\\Surface \ Area \ of \ cylinder = 395.64+307.72\\Surface \ Area \ of \ cylinder = 703.36 \ mm^2[/tex]
So, surface are of cylinder having height 9 mm and radius 7 mm is 703.36 mm²
