Lateral area of a pyramid: 1/2(perimeter · height)

Find the perimeter of the base ⇒ 24 + 24 + 24 + 24 = 96 cm

It shows that the slant height is ⇒ 16 cm

Plug these numbers into the LA formula of a pyramid.

1/2(96 · 16) = 768 cm²

The lateral area is 768 square centimeters.

Anestetic [448]

Answer: See explanation

Step-by-step explanation:

Total number of children = 369

Percentage of children on museum trip = 20%

Number of children on museum trip = 20/100 × 369

= 1/5 × 369

= 73.8 = 74 approximately

Number of children in school = 369 - 73.8 = 295.2 = 295 approximately

Answer:

Volume of cone = 200.96 square feet

Step-by-step explanation:

We are given the following information in the question:

The tree is cone shaped and has a radius of 4 feet.

r = 4 feet

The height of the tree is three times its radius.

$h = 3\times r = 3\times 4 = 12\text{ feet}$

Volume of tree =

$\text{Volume of cone} = \displaystyle\frac{1}{3}\pi r^2 h$

Putting all the values, we get,

$\text{Volume of tree} = \displaystyle\frac{1}{3}\pi (4)^2 (12)\\\\= \frac{1}{3}\times 3.14\times 4\times 4\times 12 = 200.96\text{ square feet}$

Radius of cone whose height is is equal to three times its radius is given as:

$V = \displaystyle\frac{1}{3}\pi r^2 h\\\\V = \displaystyle\frac{1}{3}\pi r^2 (3r)\\\\3V = 3\pi r^3\\\\ r = \sqrt[3]{\frac{3V}{3\pi}}$
