Question

circumference of a circle is 22 cm. Find radius and area.Please!!

Answer 1

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐

Given, circumference of circle = 22 cm.

Also, we know circumference = 2πr (where, π = 22/7 and r means radius)

So, 2πr = 22
=> 2 × (22/7) × r = 22
=> 44/7 × r = 22
=> r = (22×7/44) cm = 3.5 cm

So, radius of that circle = 3.5 cm.

Now, Area of circle= πr²

= ((22/7)×(3.5)²) cm²

= ((22/7)×12.25) cm²

= (22 × 1.75) cm²

= 38.5 cm² (Required Answer)

Answer 2

$\huge\pink{\mathfrak{Bonjour!!}}$

$\red{\boxed{\textbf{Circumference \:=22cm}}}$

$2πr=22$

$r=7/2$

$r=3.5$

$\huge\green{Area\:Of\:Circle:}$

$πr^{2}$

$22/7× 3.5×3.5$

=>38.5 $cm^{2}$
