The area of the circle is 28.26 in²

<u>Explanation:</u>

Given:

Radius of the circle, r = 3 in

Area of circle, A = ?

We know:

Area of circle = πr²

The value of π is 3.14

Thus,

A = 3.14 X (3)²

A = 3.14 X 9

A = 28.26 in²

Therefore, the area of the circle is 28.26 in²

Answer:

$P = 4\sqrt{13}$

Step-by-step explanation:

Given

$W = (7, 2)$

$X = (5, -1)$

$Y = (3, 2)$

$Z =(5, 5)$

Required

The perimeter

To do this, we first calculate the side lengths using distance formula

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2$

So, we have:

$WX = \sqrt{(5- 7)^2 + (-1 - 2)^2$

$WX = \sqrt{13}$

$XY = \sqrt{(3-5)^2 + (2--1)^2}$

$XY = \sqrt{13}$

$YZ = \sqrt{(5-3)^2 + (5-2)^2}$

$YZ = \sqrt{13}$

$ZW = \sqrt{(7 - 5)^2 + (2 - 5)^2}$

$ZW = \sqrt{13}$

The perimeter is:

$P = WX + XY + YZ + ZW$

$P = \sqrt{13}+\sqrt{13}+\sqrt{13}+\sqrt{13}$

$P = 4\sqrt{13}$

Use the function rule z = 2x + 3.

musickatia [10]

Step-by-step explanation:

Z = 2x + 3

Putting value of x

Z = 2( - 16.7) + 3

Z = - 33.4 + 3

Z= - 30.4

What is the initial value of the function:<br> f(x)=3/2(2)^x

Marina CMI [18]

Answer:

the initial value -- f(0) -- results in a value of 1.5

Step-by-step explanation:

f(0) = $\frac{3}{2}$ · $2^{x}$ (any value raised to the power of zero equals one)

f(0) = $\frac{3}{2}$ · 1

f(0) = 3/2 or 1.5
