Scott wants to buy fencing to place around a circular rock garden. The diameter of the circle is 16 feet. Using 3.14 for π, Calculate the amount of fencing Scott will need to buy?

Explain your answer and how you found it in a complete sentence.

Solution:

Given that,

Scott wants to buy fencing to place around a circular rock garden

The diameter of the circle is 16 feet

The amount of fencing Scott will need to buy is equal to the circumference of circular garden

The circumference of circle is given as:

Where, "d" is the circumference of circle

From given,

d = 16 feet

Therefore,

Thus, Scott needs to buy 50.24 feet of fencing

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
