Answer:
450 m^2
Step-by-step explanation:
let the length be y m (the single side)
let the width be x m
so according to the question
2x + y = 60
or, y = 60 - 2x
now, Area = xy
= x(60-2x)
= -2x^2 + 60x
d(Area)/dx = -4x + 60
= 0 for a max of area
-4x + 60 = 0
x = 15
then y = 30
the width has to be 15 m, and the length has to be 30 m for a maximum area of 15(30) or 450 m^2.
Answer:
i dont kno anything
Step-by-step explanation:
Answer:
B is the right answer
Step-by-step explanation:
The difference between the volume of a sphere and a cylinder is 2/3
take 30 x 2 = 60
60/3 = 20
The Volume of the Sphere is 20 m ^3
Hope this helps.
3 = $9.81
1 = $?
To find this you have to do 9.81/3.
Hope this helps and have a nice day!!
