pie r squared

that's a circle

#

Yes it is

#

Potato is basically circle

#

model the curve using an equationt

#

then rotate 360 degrees about the x axis

#

and integrate

#

#

i think thats the best way to do it but how do i get the equation

ancient relic
#

Peel it and find the area of the peels

oh you asked for surface area

#

hmm

#

could probably find something in the formula book

pie x a x b

#

Pheraps could use a polar equation

#

Idk tbh

Using a eureka can

#

But idk I ain’t done a level math yet 😭😭

#

So dk bout surface areas of goofy shapes

I just need to know how much wrapping paper i need. Its a gift for my younger brother for his birthday

in the modelling world of maths we assume it is

#

Physicists would just model it as a cylinder before they've even read the question

into a bunch of strips

#

and measure the surface area of the strips

#

if you want to go all out you can assume the potato is symetrical and try using this and measure half the length on each axis for a b c

#

this is just an approximation for an ellipsoid based on the surface area of a circle i think

#

the actual formula is aids

thats smart

Holy shite

Reminds me of a biology question where you have to estimate surface area of a leaf
