Answer:
The volume of the solid is the volume of the prism minus the volume of the cylinder.
For the cylinder, diameter = d = 4 cm
radius = d/2 = (4 cm)/2 = 2 cm
V = volume of prism - volume of cylinder
The volume of a prism is length times width times height.
The volume of a cylinder is pi times the square of the radius times the height.
V = LWH - (pi)r^2h
V = 6 cm * 6 cm * 15 cm - (pi)(2 cm)^2(15 cm)
V = 540 cm^3 - 60pi cm^3
V = (540 - 60pi) cm^3
19.18/2.8= 6.85 hours or rounded it would be 7 hours

Radical means square root, so
3 radical 16 = 3%2Asqrt%2816%29
The square root of 16 is either 4 or -4.
Thus 3%2Asqrt%2816%29+=+3%2A4+=+12
or 3%2Asqrt%2816%29+=+3%2A-4+=+-12

"Radical" doesn't necessarily mean square root. A radical is a surd, so the index may not necessarily be 2.
3 radical 16 might mean root%283%2C16%29+=+root%283%2C+8%2A2%29+=+2root%283%2C2%29.
