A cake has a circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate pi. Round to the nearest hund

s344n2d4d5 [400]

Answer:

Step-by-step explanation:

$Circumference=25\frac{1}{7}\\\\\i \pi*d=\frac{176}{7}\\\\\frac{22}{7}*d=\frac{176}{7}\\\\d=\frac{176*7}{7*22}\\\\d=8$

r = 8/2 = 4 inches

Area=πr²

$=\frac{22}{7}*8*8\\\\=\frac{1408}{7}\\\\=201.14 inches^{2}$

Find the surface area no links no pdfs just type it into the answer section will give brainliest

rewona [7]

Check the picture below.

let's firstly convert the mixed fractions to improper fractions.

$\stackrel{mixed}{7\frac{1}{2}}\implies \cfrac{7\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{15}{2}} ~\hfill \stackrel{mixed}{12\frac{1}{2}}\implies \cfrac{12\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{25}{2}} \\\\[-0.35em] ~\dotfill$

$\stackrel{\textit{\Large Areas}}{\stackrel{two~triangles}{2\left[ \cfrac{1}{2}\left(\cfrac{15}{2} \right)(10) \right]}~~ + ~~\stackrel{\textit{three rectangles}}{(10)(15)~~ + ~~\left( \cfrac{15}{2} \right)(15)~~ + ~~\left( \cfrac{25}{2} \right)(15)}} \\\\\\ 75~~ + ~~150~~ + ~~112.5~~ + ~~187.5\implies \boxed{525}$

Answer:

The "inverse operation" is just a way of saying "what do you do to isolate the variable". In this case, we isolate y, so we have to move all terms to the right side. To do that, we subtract 12 from each side to there will only be "y" on the left side.
