Find the surface area of a melon with circumference of 18 in. Round your answer to the nearest square inch.

Answers

Answer 1

Answer:

that is, the length down the middle of the melon is 18.

$\bf \textit{circumference of a circle}\n\n C=2\pi r~~ \begin{cases} r=radius\n \cline{1-1} C=18 \end{cases}\implies 18=2\pi r\implies \cfrac{18}{2\pi }=r\implies \cfrac{9}{\pi }=\boxed{r} \n\n[-0.35em] ~\dotfill$

$\bf \textit{surface area of an sphere}\n\n A=4\pi r^2~~ \begin{cases} r=radius\n \cline{1-1} \boxed{r}=(9)/(\pi ) \end{cases}\implies A=4\pi \left( \cfrac{9}{\pi } \right)^2\implies A=4\pi \cdot \cfrac{81}{\pi ^2} \n\n\n A=4\cdot \cfrac{81}{\pi }\implies A=\cfrac{324}{\pi }\implies A\approx 103.13\implies \stackrel{\textit{rounded up}}{A=103}$

Answers

Simple....

he spent $(4)/(7)$ on shoes that cost $48...

if that was $(4)/(7)$ of his money...

12*4=$48

12*7=$84

Thus, he had $84 at first.

Can someone pass me the answers my calculator died and some online don't work

Answers

I've read all of them carefully.
A calculator won't help you do 1-4.
It might be a little bit useful for 5 and 6, but only slightly. If you know your math then you shouldn't have any trouble with those either.

Paulina works out with a 2.5-kilogram mass. what is the mass of 2.5-kilogram mass in grams?

Answers

Kilo means thousand, so if you have 1 kilogram that means you have 1000 grams.

Paulina has a 2.5 kilogram mass, 2 kilograms is 2000 grams.

0.5 means half and to get a half out of anything you have to divide it by 2.
1000 divide by 2 is 500.

Your answer is 2500.
