Cone, diameter of base 18 ft slant height 14 ft
1 answer:
Answer:
207π ft²
Step-by-step explanation:
Given in the question,
diameter of the base = 18 ft
slant height= 14 ft
radius of the base = 18/2
= 9 ft
Formula to calculate the surface area
<h3>A = πrl+πr²</h3>
<em>here l = slant height</em>
<em> r = radius of the base</em>
<em />
plug values in the formula
A = π(9)(14)+π9²
A = 207π ft²
