Please help!!
garik1379 [7]

Given:

The radius of the cone = 14 ft

The slant height of the cone = 27 ft

To find the lateral surface area and the total surface area of the given cone.

Formula

The lateral surface area of the cone is

LSA = \pi rl and

The total surface area of the cone is

TSA = \pi r^{2} + \pi r l

where,

r be the radius and

l be the slant height of the cone.

Now

Taking r = 14 and l = 27 we get

LSA = \pi (14)(27) sq ft

or, LSA = 1187.5 sq ft

Again,

TSA = \pi(14^2)+\pi (14)(27) sq ft

or,TSA = 1803.3 sq ft

Hence,

The lateral surface area of the cone is 1187.5 sq ft and the total surface area of the cone is 1803.3 sq ft. Option C.

Brilliant_brown [7]
Hello,

N is closed for an opération(µ)  means that
a,b ∈ N : a µ b ∈N (i suppose so)

Answer (1) ex 2/3 ∉ N

Answer (4) ex 2-3 ∉ N

∀ a,b ∈ N: a+b ∈N is true ; not a answer.

∀ a,b ∈ N: a*b ∈N is true ; not a answer.
