circumference = 2pie r
44 = 2 × 22/7 × r
r = 44/2 × 7/22
r = 7
area of circle = pie r^2
= 22/7 × 7 × 7
= 154 cm^2
44 = 2 × 22/7 × r
r = 44/2 × 7/22
r = 7
area of circle = pie r^2
= 22/7 × 7 × 7
= 154 cm^2

Circumference of circle=2×22/7×r
44=2×22/7×r
r=44×7/44
r=7cm
Area of circle=22/7×r*2
=22/7×7×7
=22×7=154cm sq.
44=2×22/7×r
r=44×7/44
r=7cm
Area of circle=22/7×r*2
=22/7×7×7
=22×7=154cm sq.
can u tell me one more question
