Question

the shape of the top of a table in a restaurant is that of a segment of a circle with Centre O and Angle BOD equal to 90 degree. BC =OD=60 CM . then find the area of the top of the table and the perimeter of the table​

Answer 1

answer;

Perimeter of the table =43×2πr+2r

=43×2×722×60+2×60

=4×73×2×22×60+120

=73×11×60+120

=282.85+120

=402.85cm

Answer 2

Answer:

The area is 8478 cm².

Step-by-step explanation:

First find the area of sector:

=90/360*3.14*3600 (Here 90 is the angle at the centre O)

= 2826 cm²

Then find area of circle

=3.14*3600

= 11,304 cm²

Then subtract to get area of table top:

11304-2826= 8478 cm²

For perimeter follow the 2nd answer
