Answer:
Step-by-step explanation:
the smallest length that the pen could be is the with x length => 209 sq ft
where the length is 8 feet more than the width.
so find that where x *( x+8) = 209
then + 8x - 209 = 0
using the quadratic equation I got 11
11* ( 11+8) =209
so that's the smallest it could be
so the width must be greater than 11 to make the pen greater than 209 sq ft. :)
Answer:
Step-by-step explanation:
The formula of a volume of a cylinder:
r - radius
H - height
We have the radius r = 12cm and the height H = 20cm. Substitute:
The formula of a volume of a cone:
r - radius
H - height
We have the radius r = 8cm and the volume V = 2880πcm³. Substitute:
