Answer:
V = 72.3 m³
Step-by-step explanation:
The formula for the volume of a right circular cone is
V = (1/3)(base area)(height). Here,
V = (1/3)(π[4.4 m]²)(11.2 m), or
1 * π * 19.36 * 11.2 m³
V = -------------------------------

Evaluating this on a calculator, we get:
V = 72.3 m³

Step-by-step explanation:
Since, △ABC is a right angled triangle. We can apply Pythagoras' Theorem to find the length of AB.
According to Pythagoras’ theorem, “In a right angled triangle: The square of the hypotenuse is equal to the sum of the squares of the other two sides.”
Applying Pythagoras’ theorem in △ABC, we get
AB2=AC2+BC2
⇒AB2=52+122
⇒AB2=25+144
⇒AB2=169
⇒AB=169−−−√
⇒AB=13 cm
