Formula: A = pi times r^2 the radius would be 4 because you divide 8 by 2 in order to get radius. a = pi (4^2) a = pi (16) a = 3.14 (16) area = 50.24cm ^2

The area is 50.24 cm.
The formula is π·r^2.
The radius is 4 cm, and you square it. 16 cm.
Then you multiply 16 by 3.14 (π). And you get 50.24 cm as the area.

The force on an area 16 m by 12 m is 24,000 N. What is the pressure per square meter?

Dmitrij [34]

Recall that
Pressure = Force ÷ Area

In this context we have,
Pressure = 24,000 ÷ (16 × 12)
= 24,000 ÷ 192
= 125 Pa

A rectangle has an area of 12 square feet and a length of 5 feet. What is its width?

Lera25 [3.4K]

Well, you know that the area of the rectangle is 12 square feet. And you know one of the numbers multiplied to get 12 is 5, so divide 12 by 5. You would get 2.4 as the other number needed.
In this case, 5 feet is the width and 2.4 feet is the length.

Answer:

In a nutshell, $g(x) = x+2$ .

Step-by-step explanation:

A composition is operation between function that consist in replacing the independent variable of the first function, $f(x)$ in this case, for $g(x)$ . Common notations for composition between functions are $f(g(x))$ and $f\circ g (x)$ . If we know that $h(x) = f\circ g (x) = (x+2)^{2}$ and $f(x) = x^{2}$ , then $g(x) = x+2$ .

In a nutshell, $g(x) = x+2$ .
