help please i dnt understand

Answer 1

What solid do you think you can make with the given material ?

Answer 2

a cylinder?

Answer 3

SA = 2* pi*r^2 + 2*pi*r*L

Answer 4

the radius would be one inch?

Answer 5

and would tht be surface area fr the circle or the whole thing

Answer 6

Yes you are right its a cylinder .... the radius will be 1 inch and that will give you the surface area for whole thing ..Make sure you understand how we got that .Any doubts?

Answer 7

i dnt kno hw u gt tht cn u clearify plzz

Answer 8

SA = 2* pi*1^2 + 2*pi*1*L ?

Answer 9

area pf circle = pi *r*r

now here 2 circles for cylinder so 2*pi *r*r

now the curved area =2*pi*r*l

total surface area =2* pi*1^2 + 2*pi*1*L

Answer 10

I got surface area 8pi
And volume 3pi
