Answer:

Step-by-step explanation:

Circumference = 2πr

Let's set the equation equal to the formula:

16 = 2πr

16/2 = πr

8 = πr

r = 8/π

Consider the exponential function f(x) = 2(3x) and its graph.
AveGali [126]

Answer:

The initial value of the function is <u>2</u>

The base of the function is <u>3</u>

The function shows exponential <u>growth</u>

Step-by-step explanation:

f(x) = 2(3^x)

Exponential functions are those with the following equation:

y = a*b^x

where a ≠ 0, b > 0 and b ≠ 1 and x is a real number.

<em>a</em> is the y-intercept and <em>b </em>is the base.

The initial value of the function is the same as the y-intercept

If <em>a</em> is positive, the function growth. If <em>a</em> is negative, the function decay

A circle has a circumference of 28π centimeters. In terms of π, what is the area of the circle to the nearest square centimeter?
Vadim26 [7]

Hi there!

The formula to find the are of a circle is :

a = \pir²

The formula to find the circumference of a circle is :

c = 2\pir


In order to use the area formula, you need to figure out what the radius (r) is.

If we solve for "r" in the circumference equation, we have :

r = c ÷ (2\pi)


Now we use this to replace "r" in the area formula :

a = \pi ( c ÷ (2\pi))²


When we simplify this we get :

a = c² ÷ 4\pi


Now you can put your value of "c" into this equation and find "a".

*Remember, \pi is about 3.1416.


Solving for "a" :

a = c² ÷ 4\pi

a = 28² ÷ 4\pi


28² = 28 × 28 = 784


a = 784 ÷ 4\pi


4\pi = 4 × \pi = 12.56637061435917


a = 784 ÷ 12.56637061435917

a = 62.38873769202297cm²


You need to round to the nearest square centimeter, which means that you need to round to the nearest whole number :

a = 62cm²


There you go! I really hope this helped, if there's anything just let me know! :)
