Question

Draw a circle of radius 3.5 cm. Using a thread find its circumference. Also verify the
relation C = 3.14 x d (approximately).
There are 7 round tables at a party. The radius of each table is 20 cm. How much​

Answer 1

Answer:

Steps of Construction :

1. Draw a circle of radius 3.5 cm from centre pointO

2. Set a point P which is located at distance 6.2 cm from point O. Join OP.

3. Draw a perpendicular bisector of OP which cuts OP at point Q.

4. Now, considering Q as a centre and equal radius (OQ=PQ).Draw a circle.

5. Both circles intersect at points A and B.

6. Join PA nd PB.

Therefore, AP and BP are the required tangents.

Answer 2

Step-by-step explanation:

R=3.5

=3.5×3.14=10.99÷3.14
