Question

2.
Find the circumference of a circle whose diameter is
(iii) 10.5m​

Answer 1

Answer:

circumference equal to 2πr

radius = 10.5/2

radius= 5.25

2πr = 2×π× 5.25

33 is the correct answer of this question.

Answer 2

Answer:

Step-by-step explanation:

formula : 2*3.14*r

d= 10.5m = 10.5*100=1050cm

r=d/2 = 525cm

c= 2*3.14*r

=2*3.14*525

3297cm or 32.97 m
