Answer :
Answer:
[tex] A= 2\pi (3cm)^2 +1 2\pi (3cm)(10 cm)= 18 \pi + 60\pi = 78 \pi cm^2[/tex]
And replacing the value of [tex]\pi =3.14[/tex] we got:
[tex] A = 78*3.14 cm^2= 244.92 cm^2[/tex]
Step-by-step explanation:
For this case we have the long who represent the height 10 cm and the diameter is 6cm. So then the radius is given by:
[tex] r = \frac{D}{2}= \frac{6cm}{2}= 3cm[/tex]
And the surface area for a cylinder is given by this formula:
[tex]A= 2\pi r^2 +2 \pi rh[/tex]
And replacing the info given we got:
[tex] A= 2\pi (3cm)^2 +1 2\pi (3cm)(10 cm)= 18 \pi + 60\pi = 78 \pi cm^2[/tex]
And replacing the value of [tex]\pi =3.14[/tex] we got:
[tex] A = 78*3.14 cm^2= 244.92 cm^2[/tex]
