For this case we have that by definition, the surface area of a cone is given by:
Where:
A: It's the radio
s: It's the slant
Substituting according to the data we have:
If we round:
Answer:
True
Looks good to me. Calculation is correct. Although you might want to add to #1 your description; that the width of the rectangle is the circumference of the circle (w = 2πr) and that you add the surfaces together to get the total surface area.
total surface area = area of rectangular part + area of circular parts
SA = 2πrL + 2πr²
Answer:
I think its 12 to this question
Answer:what are all the choices
Also it’s 0
Step-by-step explanation:
Figure B is the answer!
The formula for the Pythagorean theorem is
