# For the accompanying right circular cone, h = 6 m and r = 4 m. Find the exact and approximatea) lateral area.b) total area.c) volume. To determine

(a)

To find: The exact and approximate lateral area of the right circular cone.

Explanation

Given:

Consider a right circular cone with h=6 m and r=4 m.

Formula used:

In a right circular cone r2+h2=l2.

The lateral area of the right circular cone is L=πrl

Calculation:

We have h=6 m and r=4 m.

Substitute the known values in the formula,

r2+h2=l242+62=l216+36=l2<

To determine

(b)

To find: The exact and approximate total area of the right circular cone.

To determine

(c)

To find: The exact and approximate volume of the right circular cone.
