Can someone help me find the area of this circle and round to the nearest tenth

larisa [96]

the circle has a diameter of 12, thus its radius is half that, or 6.

$\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=6 \end{cases}\implies A=\pi 6^2\implies A=36\pi \\\\\\ A \approx 113.0973355\implies A=\stackrel{\textit{rounded up}}{113.1}$

A large pizza at Little Italy costs $7.00 plus $0.80 for each topping. The cost of a large cheese pizza at Spinato's is $7.60 pl

laiz [17]

At the start you will start with $7 and $7.60 there is a simple way and a more complex process. The simple way is using the formula of y=mx+b so y=.8x+7 and the other way is just too add .8 to 7 and .7 to 7.6 and keep doing that till you get the answer. The answer is 7, seven topping have to be added to make them the same price.

Pure 24K gold is worth $1050/oz.
