Question

12. Answer any two questions :
The length of a radius of a circle is 28cm. Determine the cire
angle subtanded by an arc of length 5.5cm at the centre of the circle​

Answer 1

Step-by-step explanation:

R= 28cm

D=R/2

=28/2

=14cm -5.5cm

= 8.5cm ans

Answer 2

Answer:

radius of a circle is 28cm

given that 5.5cm is subtanded

hence ... D =r/2

D=28/2 which is equal to 14 cm

now substract 5.5 cm

(14-5.5)cm =8.5cm Ans
