What is the area of a circle with a diameter of 6x? (Use 3.14 for R

aksik [14]

The area of a circle is defined as Pi R^2

Since we only have the diameter and Pi, we need to solve for the radius.

The radius is 1/2 of the diameter, so divide 6 by 2 to get our radius.
6 / 2 = 3

Our radius is 3.

Now let's plug in our formula.

A = 3.14 x 3^2

3 x 3 = 9
9 x 3.14 = 28.26

Your area is 28.26 units ^2

I hope this helps!

Which function is increasing?? :)

exis [7]

Answer:

$\large\boxed{B.\ f(x)=4^x}$

Step-by-step explanation:

Exponential function $f(x)=(a)^x$ is

increasing if $a > 1\to a\in(1,\ \infty)$

decreasing if $0 < a < 1\to a\in(0,\ 1)$

$A.\ f(x)=\left(\dfrac{1}{4}\right)^x\to a=\dfrac{1}{4}\in(0,\ 1)\to\text{decreasing}\\\\B.\ f(x)=4^x\to a=4\in(1,\ \infty)\to\text{increasing}\\\\C.\ f(x)=(0.4)^x\to a=0.4\in(0,\ 1)\to\text{decreasing}\\\\D.\ f(x)=\left(\dfrac{1}{2}\right)^x\to a=\dfrac{1}{2}\in(0,\ 1)\to\text{decreasing}$
