Answer 1

Step-by-step explanation:

since, 38 × 38 = 1444 ; which is less than 1500

39 × 39 = 1521 ; which is greater than 1500

Therefore, we must add 21 to 1500 to get a perfect square which is 1521

and the root of 1521 is 39.

Answer 2

Diameter of circle =1.26m

travel distance=circumference of circle ×500 revolution

circumference of circle = one relvolution

now,

according to questions (A.T.Q),

finding distance,

circumference of circle = 2πr

=2×22/7x(1.26/2)

=3.96

distance in 500 revolution = 3.96×500

=1980.00
