A square pyramid has a base side of 12 in. and a slant height of 15 in. The lateral area of the pyramid is _____ in.².

1 answer:

3 0

Solving for the lateral surface of the square pyramid, we need to use the formula shown below:
Lateral Area = a √ (a² + 4h²) where "a" for the base edge and "h" for the height

We have given values such as:
Base = 12 inches
Height = 15 inches
Lateral area = 12 √ (12² + 4*15)
Lateral area = 171.39 inches²

The answer is 171.39 inches².

What is the area of the rectangle with the given dimensions? *

exis [7]

Given:

The dimensions of a rectangle are $2x-5$ and $3x+3$ .

To find:

The expression that represents the area of the rectangle in simplest terms.

Solution:

Area of a rectangle is:

$Area=Length\times Width$

The dimensions of a rectangle are $2x-5$ and $3x+3$ . So, the area of the given rectangle is:

$Area=(2x-5)\times (3x+3)$

$Area=2x(3x)+2x(3)-5(3x)-5(3)$

$Area=6x^2+6x-15x-15$

$Area=6x^2-9x-15$

Therefore, the correct option is F, i.e., $6x^2-9x-15$ .

Is 1/3, 2/3, 4/3, 8/3, 16/3 arithmetic sequence

11111nata11111 [884]

The given sequence is not arithmetic sequence

Solution:

Given sequence is:

$\frac{1}{3} , \frac{2}{3} , \frac{4}{3} , \frac{8}{3} , \frac{16}{3}$

We have to find if the above sequence is arithmetic sequence or not

An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant

Here in the given sequence

$\text{ first term } = a_1 = \frac{1}{3}\\\\\text{ second term } = a_2 = \frac{2}{3}\\\\\text{ third term } = a_3 = \frac{4}{3}\\\\\text{ fourth term } = a_4 = \frac{8}{3}\\\\\text{ fifth term } = a_5 = \frac{16}{3}$
