Area of a circle is 49πcm2. Find its circumference |
|
Answer» As per STATEMENT the area of a CIRCLE is 49 pie cm square. It means We know Area of circle is πr², where r is the RADIUS of the circle πr^2 = 49π r^2 = 49π/π r^2 = 49 r = √49 r = 7 cm The radius of the circle is 7 cm. We know Circumference of a circle is 2πr, where r is the radius. Accordingly Circumference = 2πr Circumference =2 × 22/7 × 7 Circumference =44 × 7/7 Circumference = 44 cm Answer : the circumference of the circle is 44 cm. |
