What is the approximate circumference of the circle shown below?

D. 148 cm

Step-by-step explanation:

The equation to find the circumference is C = 2(π)(r)

C = 2 (3.14) (23.5)

C = 147.58, when rounding, your answer is 148 cm.

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}
