Answer:

2772 cm²

Step-by-step explanation:

Work:

2(π x 21 x 21/2) + (π x 42 x 42/4) = Area of figure
=> π x 21 x 21 + (π x 42 x 42/4) = Area of figure
=> (22/7 x 21 x 21) + (22/7 x 21 x 21) = Area of figure
=> 2(22/7 x 21 x 21)
=> 2(22 x 3 x 21)
=> 2772 cm²

Hence, the area of the shape is 2772 cm².

Answer:

0.16

Step-by-step explanation:

Length = 5 units
Number of broken sticks= 3
Equal lengths = 5 units/3

See the picture attached for reference.

As you see the best points are the green areas which covers 2 out of 5 zones.

Since it is same for both broken points, the probability of this is:

2/5*2/5 = 4/ 25 = 0.16

Answer is 0.16
