Question

find the area of circle whose diameter is 17cm​

Answer 1

Diameter = 17 cm

Radius = 17/2 = 8.5 cm

Area of circle = πr²

Area of circle = 3.14 × (8.5)²

Area of circle = 3.14 × 72.25

Area of circle = 226.865 cm²

Answer 2

Answer:

226.865

Explanation:

We know that radius is half of the diameter of a circle

Hence, r=8.5 cm

Area = pi*r*r

Area=3.14*72.25

Area=226.865 cm
