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>

What is the area of this composite figure, in square centimeters?<br> 176<br> 209<br> 242<br> 264
e-lub [12.9K]

Answer:

209

Step-by-step explanation:

We can divide the figure into 2 parts to make this easier.

11x16=176 so the square is 176 square cm.

(11x6)/2 = 66/2 = 33 so the triangle is 33 square cm.

176+33 = 209 sq cm.

natita [175]

Answer:

see explanation

Step-by-step explanation:

(1)

The sum of the 3 angles in a triangle = 180° , thus

a + b + c = 180

(2)

adjacent angles are supplementary, thus

b + d = 180

(3)

From (1) and (2)

b + d = a + b + c ( subtract b from both sides )

d = a + c
