Question

use a calculator to determine upto two decimal places,the primeter and the area of the circle

Answer 1

hey!!
the perimeter or the circumference of the circle is 2πr.= 2×3.14 /r
=6.28


area of the circle= πr²
3.14×r2
3.14r2..

you can put the given value of radius or diameter(d/2=r)
the values are up to two decimal places because the value of π= 3.142...
after rounding off..it will come 3.14

hope it helps!! :)

Answer 2

perimeter of circle = 2πr²
= 2×3.14×r² = 6.28r²
area of circle= πr²
= 3.14×r²
