In-s [12.5K]

Based on the calculations, the volume of this louvre pyramid is equal to 8,983 cubic meter..

<u>Given the following data:</u>

Base width = 35 meters.

Height = 22 meters.

<h3>How to calculate the volume of a pyramid?</h3>

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × base area × height

For the base area, we have:

Area = w²

Area = 35² = 1,225 m².

Substituting the parameters into the formula, we have;

Volume = 1/3 × 1,225 × 22

Volume = 1/3 × 26,950

Volume = 8,983 cubic meter.

What is the lateral area of the cone to the nearest whole number? The figure is not drawn to
Sveta_85 [38]

Answer:

The lateral surface area of the cone is 25120\ m^2.

Step-by-step explanation:

We have.

Height of a cone is 60 m

Diameter of a cone is 10 m

Radius, r = 80 m

The lateral surface area of a cone is given by :

A=\pi rl

l is slant height of the cone,

l=\sqrt{60^2+80^2} =100\ m

Plugging all values in above formula,

A=3.14\times 80\times 100\\\\A=25120\ m^2

So, the lateral surface area of the cone is 25120\ m^2.
