circumference of a circle=2πr
diameter = 49m
radius = 49/2 = 24.5 m
2×22/7×24.5
= 154m answer....
area of a circle = πr^2
22/7×[24.5]^2
= 22/7× 600.25
= 1886.5 answer....
hope this helps...

Given
Diameter of circle = 49 cm
To Find
Area of circle
circumference of circle
Solution
circumference of circle = pie × diameter
= 22/7 × 49
= 22 × 7
= 154 m
radius = diameter /2
= 49/2
Area of circle = pie × radius^2
= 22/7 × 49/2 × 49/2
= 22 × 7 × 49 /4
= 7046/4
= 1761.5 m^2
so the circumference of circle is 154 m and the area is 1761.5 m^2
Diameter of circle = 49 cm
To Find
Area of circle
circumference of circle
Solution
circumference of circle = pie × diameter
= 22/7 × 49
= 22 × 7
= 154 m
radius = diameter /2
= 49/2
Area of circle = pie × radius^2
= 22/7 × 49/2 × 49/2
= 22 × 7 × 49 /4
= 7046/4
= 1761.5 m^2
so the circumference of circle is 154 m and the area is 1761.5 m^2
