A large pizza has diameter 36 cm and a medium pizza has diameter 30 cm. What is the difference in area of the pizzas? Round your

vladimir1956 [14]

Answer:

311 $cm^{2}$

Step-by-step explanation:

Taking a pizza to be a circle

Area of big pizza be x abd are of small pizza be y

hence difference = x-y

Area of a circle = $\pi r^{2}$ where r is the radius

taking $\pi$ to be 3.14

hence area x = 3.14 ( $\frac{36}{2}$ * $\frac{36}{2}$ ) = 1017.36

Area y = 3.14 ( $\frac{30}{2}$ * $\frac{30}{2}$ )= 706.5

x-y = 1017.36- 706.5 =310.86 $cm^{2}$

310.86 $cm^{2}$

What are the domain and range of the function?<br> f(x) = ^3 square x - 3

DerKrebs [107]

Step-by-step explanation:

$f(x) = \sqrt[3]{x - 3}$

The domain of a function are the values of $x$ that you can plug into the function $f(x)$ .

Values inside of a root must be non-negative, which means that $x - 3$ must be greater than or equal to zero. We can set up an equation to find the domain:

$x - 3 \geq 0$

$x \geq 3$

With this, we know the domain of the function is $[3, \inf)$ .

The range of a function are the values that $f(x)$ can have. Since the equation is a cube root, the value will always be non-negative, meaning the range of the function is $[0, \inf)$ .
