The surface area of a cone with circumference base of 24π inches and slant height of 20 inches is 384π inches² in terms of π.
<h3>Surface area of a cone</h3>
surface area = πr(r + l)
where
- r = radius
- l = slant height
Therefore,
l = 20 inches
24π = 2πr
r = 12
Therefore,
surface area = π(12)(12 + 20)
surface area = 12π(12 + 20)
surface area = 12π × 32
surface area = 384π inches²
