Radius =4.9cm
Area of circle =
=22/7x4.9x4.9
=22x.7x4.9=75.46cm²
Area of circle =
=22/7x4.9x4.9
=22x.7x4.9=75.46cm²
DIPIT:
it's 75.43

Radius =4.9
Area of circle =2πr²
Therefore
Area=2×4.9×22/7
=30.8cm²
Area of circle =2πr²
Therefore
Area=2×4.9×22/7
=30.8cm²
formula is wrong it's 22÷7×r^2
but the area of the radius 3.14 multiple by diameter
it's not the matter the answer is 75.43
u did the mistake so I am just suggesting u
