Question

The measures of ZA and LB of a triangle ABC are 30º and 50° respectively, then the sides in
ascending order is
[ ]
a) AB <BC < AC b) BC < AC < AB C) AC < AB < BC d) AB < AC <BC
In a triangle ABC if AB = 8cm, BC = 5cm and CA = 4cm, then the descending order of angles is​

Answer 1

Answer:

ok The circumference of a circle is 2πr or πD if diameter is given.

The answer is 25.13

C=2πr

So finding for radius in this equation=diameter/2

8/2=4 cm

So now 2 × 22/7 × 4

176/7=25.13 cm

OR

C=πD

22/7 × 8

176/7=25.13 cm
