It should be 18.84. To find the circumference of a circle you would times the diameter by pi or 3.14 but since its the radius you would need to times pi (by the radius and times that by 2. so 3 times 2 is 6 and 6 times 3.14 is 18.84
Answer:
1533.88261311522
Step-by-step explanation:
<em>Let r be the radius of the (base/circle)</em>
<em>and L be the slant height of the cone</em>
<em>Formula ………………………………………………………………………………………………………</em>
The surface area of a cone = the (curved/lateral) surface area + the base

=========================================

L = BC = 36
