A) The radius of the hemisphere is:
r = d÷2 = 21÷2 = 10.5cm

We can now calculate the volume of a hemisphere:
V = 2/3 π r<span>³
   = </span> 2/3 π (10.5)³
   = 2423 cm³

As we can consider that 1000cm³ contains 1l, each bowl contains 
2423 ÷ 1000 =2.423l.
In total, the milk served will be: 2.423 × 100 = 242l

B) The total cost will be: 
242 × 10 = 2420Rs

C)<span> Mr.and Mrs. Ramesh helped blind students using an eco-friendly material, therefore they have shown social and environmental values.</span>

The answer is abd with 170. you gotta set all those angles sum as 540 wich is the sum of the angles for a pentagon. if you do that and solve for x=28 plug 28 in for 6x+2 you end up with 170

Answer:

y = \frac{\pi}{3}

Step-by-step explanation:

using the addition formula for sine

sin(x + y) = sinxcosy + cosxsiny

then

sinxcosy + cosxsiny = \frac{1}{2} sinx + \frac{\sqrt{3} }{2} cosx

for the 2 sides to be equal , then

cosy = \frac{1}{2} and siny = \frac{\sqrt{3} }{2}

then

y = cos^{-1} (\frac{1}{2} ) = \frac{\pi }{3}

and

y = sin^{-1} ( \frac{\sqrt{3} }{2} ) = \frac{\pi }{3}

thus y = \frac{\pi }{3}
