Step-by-step explanation:
2πr^2+2πrh
2(3.14)(5)^2+2(3.14)(5)(15)
2(3.14)(25)+2(3.14)(75)
2(78.5)+2(235.5)
157+471
628
It can be turned into 4•19/81 (mixed proper fractions) or in decimal 4.2346 (4dp)
You stop at 2 decimal points. If the 3rd decimal is bigger than 5, add 1 to the 2nd and if it's less than 5, keep it as it is.
For example:
2.663 --> 2.66
6.788 --> 6.79
the answer is 4.36yds. 4.36 ×4.36= 19.006
