1) surface area = 18m^2 * pi * 26m = <span>8424pi m^2</span>
if we're factoring you can use the AC method. A multiplied by C is 24. and 4x6 is 24.
(x+4)(x+6) is your answer
The 4 Pack is the better value ;)
To get the amount you need to subtract from 840, just turn 5% into a decimal, which is 0.05, then just multiply 0.05 by 840 and subtract that number from 840
To solve a mixed fraction you will have to multiply the mixed number by the denominator then add the numerator for example:
7 3/4 you are gonna go 7x4=28 then you are gonna take that 28 and add 3 to it so it would be 31. I hope that helped some c:
