Question

plz help me to find out

Answer 1

using Pythagoras theorem here, we get

AC=50cm,

therefore

radius=(AB+BC-AC)/2,

r=(14+48-50)/2,

then
r=12/2,

r=6 cm

Answer 2

explanation:

oA and oC and OB connect.then the ar (ABC)=ar (COB)+ar (BOA)+ar (COA)=1/2×48×r+1/2×14×r+1/2×50×r=24r+7r+25r=56r=336=r=6
