Find the area of the circles with : (vi) circumference = 66cm

Area = A = 65.999999999997 cm

Step-by-step explanation:

Circumference = 66 cm

Circumference = 2πr

So        2πr = 66 cm

     r = 66/2π =10.509554140127

Area of circle  = πr²   = 3.14(10.509554140127)²

Area = A = 65.999999999997

step-by-step explanation:

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
