Answer 2

$\huge\underline\textbf{Answer}$

Given,

• Circumference of circle = 44 cm

To find,

• Area of circle = ?

Formulas to be used here,

• Circumference of circle = 2πr
• Area of circle = πr²

Solution,

→ Circumference of circle = 2πr

→ 44 cm = 2πr

→ 44/2 cm = πr

→ 22 = πr

→ r = 22×22/7 (22 will be cancelled with 22)

→ r = 7

★ Radius = 7

★ Now,we will find area of circle.

→ Area of circle = πr²

→ Area of circle = 22/7×(7)² = 22/7×49

→ Area of circle = 154 cm²

★ Area of circle = 154 cm²

$\huge\underline\textbf{Formulas}$

★ Circumference of circle = 2πr

★ Area of circle = πr²

★ Radius of circle = Diameter/2
