What is the volume of a cone with the given dimensions?<br> Diameter = 14 cm.; Height = 2 cm.

Helga [31]

Volume of a cone = (π.R²)(h/3)

Diameter = 14cm then R=7 cm

Height = h= 2cm

Hence V=*π.7²)(2/3) ==> 98π/3 or 102.625 cm³

Each side of a square is increasing at a rate of 6cm/s. At what rate is the area of the square increasing when the area of the s

diamong [38]

Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
