A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28
cm, which quadratic equation best models the volume of the box?
V = lwn
P = 2(1 + w)
y = 5(28 - x)(x)
y = 5(28 - 2x)(x)
y = 5(14 - x)(x)
y = 5(14 - 2x)(x)

a

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
