Answer:
113.115 cm
Step-by-step explanation:
<u>Formula:</u>
C = 2πr
<u>Given:</u>
Radius: 22 cm
Diameter: 44 cm
The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter.
Simply plug in your numbers to find the circumference first.
C = 2π(22)
C = 44π cm or 138.23 cm
Then, divide the circumference in half, and add your diameter.
Perimeter = (44π/2) + 44 = 113.115 cm
Answer:
x² - 2
Step-by-step explanation:
To obtain (g ○ f)(x), substitute x = f(x) into g(x), that is
g(x² - 3)
= x² - 3 + 1
= x² - 2
<h2>
Answer:</h2>
The derivative of the function f(x) is:

<h2>
Step-by-step explanation:</h2>
We are given a function f(x) as:

We have:

( Since,
)
Hence, we get:

Also, by using the definition of f'(x) i.e.

Hence, on putting the value in the formula:

Hence, the derivative of the function f(x) is:
