Question

1 Find the area of a circle, if
Radius (r) = 14 cm, Diameter = 10 cm​

Answer 1

1→ radius = 14cm

area of circle = π×14×14

area of circle= 22/7×14×14

area of circle = 22×2×14

area of circle = 616cm²

2→ diameter = 10cm

radius = 5cm

area of circle = π×5×5

area of circle 22/7×5×5

area of circle = 78.57cm²

Answer 2

Answer:

Area of circle = πr² sq.units

Step-by-step explanation:

Area = 22/7 x (14)² cm²

         =616 cm²

When diameter = 10 cm , then radius = 10/2 cm =5cm

Area=22/7 x (5)² cm²

        =78.57 cm²
