noname [10]

Answer:

30 cm²

Step-by-step explanation:

we need to find h

V=πr²h

h=V/πr²

h=210/14²π

h=0.341

then we found curved surface area

A=2πrh

A=2×π×14×0.341

curved surface are= 30 cm²

Answer:

The green would take 4 and the blue would take 16 times respectivly. I did it by finding the volumes of the cups in terms of pi, then dividing it by the volume of the sink.

Step-by-step explanation:

So the volume of the whole half sphere is 512pi.

Now we have to find the volumes of the cup.

Equation: $\pi r^2h$

Blue cup:

$\pi 2^2(8)\\\pi 4(8)\\\pi 32$

It would take 16 times to drain it completly.

Green cup:

$\pi 4^2(8)\\\pi 16(8)\\\pi 128$

It would take 4 times to drain it completly.
