area = 0.5ab = 210

ab = 420

a = 420/b = 420/21 = 20 ft

length of hypotenuse = √(a²+b²) = √(20²+21²) = √841 = 29 ft

Answer:

Step-by-step explanation:

Volume of first container = 48 cm³

πr²h = 48 cm³

Second container:

height = (2/3)h

Volume of second container=

$=\pi *r^{2}*(\frac{2}{3}*h)\\\\=\frac{2}{3}*\pi *r^{2}*h\\\\$

=(2/3)* first container's volume {πr²h = 48 cm³}

$=\frac{2}{3}*48\\\\=2*16\\\\$

= 32 cm³
