Answer:
0.4
Step-by-step explanation:
Divide 2 by 5
The triangle formed from the height of the cone and the radius of its base is a special 3,4,5 triangle. The slant height is 5cm.
Recall that the area of a circle = pi*r^2
Substitute 3 in for r
Area = pi * (3)^2 = 9pi
SA = pi*r*l + B
Substitute our values into the equation
SA = pi * 3 * 5 + 9pi
SA = 15pi + 9pi
SA = 24pi cm^2
You can just use the tn formula to solve this tn= t1 + (n-1)d
Is this homework?
You can always go back in the lesson what you have learned and or ask your parents.
Sorry for not really answering you're question. I have no idea. I'm sorry.
