the perimeter of a square whose area is equal to that of a circle with parimeter 44/7x is
Answers
perimeter of square= 4 x side
44 cm = 4 x side
side =44 / 4
side of square = 11 cm
area of square = side x side
= 11 x 11
= 121 cm²
circumference of circle = 2 π r
44 cm = 2 π r
r = 44 / 2π
r = 22 /π
r= 22/ (22/7)
r = 22 x 7 / 22
r = 7 cm
area of circle= π r²
= (22/7) x 7 x 7
= 22 x 7
=154cm²
thus
area of circle is more
Answer:
Perimeter of square= 4 x side
44 cm = 4 x side
side =44 / 4
side of square = 11 cm
area of square = side x side
= 11 x 11
= 121 cm²
circumference of circle = 2 π r
44 cm = 2 π r
r = 44 / 2π
r = 22 /π
r= 22/ (22/7)
r = 22 x 7 / 22
r = 7 cm
area of circle= π r²
= (22/7) x 7 x 7
= 22 x 7
=154cm²
