Question

In fig. Four congruent circles touches external and a square ABCD of side 14cm is drawn by joining the centers of circles. Find the area of shaded region. ​

Answer 1

Answer:

42 cm²

Step-by-step explanation:

I have attached the answer. Here I will give you the explanation!

First is entry the given values under appropriate headings, so it will be easy for you.

Next the value of radius is not given, but the question says that the side of square is equal to 14 cm & they gave the circles touch externally on the side of square. So the value of radius is 7cm.

Then they asked the area of shaded one.

So you need to subtract the area of quadrant from the area of square.

And you need to substitute the values given in the beginning down.

If the question gives you the value of pi then use it, otherwise you 22/7

Then calculate as given in the attachment you will get the answer as 42 cm².
