Question

A circular shape is obtained from a 44 cm long wire. What is the the radius of the circle ???????​

Answer 1

Answer:

7

Step-by-step explanation:

44=2πr

=r=44*2/2*22

=r=7.

Answer 2

$Given:-$

• $length \: \: of \: \: wire \:\: = \: \: 44 \: cm$

$To \: \: Find:-$

• $Radius \: \: of \: \: circle.$

$Solutions:-$

• $Circular \: \: shape \: \: is \: \: obtained \: \: from \: \: a \: \: 4 \: cm \: \: long \: \: wire.$

$≫ Length \: \: of \: \: wire \: = \: perimeter \: \: of \: \: circle \: = \: 44 \: cm$

• $perimeter \: \: of \: \: circle \: = \: 2πr$

$⇢ 2πr \: = \: 44 \: cm$

$⇢ πr \: = \: \frac{44}{2}$

$⇢ πr \: = \: 22$

$⇢ \frac{22}{7} \: × \: r \: = \: 22$

$⇢ r \: = \: 22 \: × \: \frac{22}{7}$

$⇢ r \: = \: 7$

• $So, \: \: Radius \: \: of \: \: circle \: \: is \: \: 7 \: cm.$

______________________________________

$≫ Some \: \: important \: \: information:-$

• $r \: = \: Radius$

• $π \: = \: \frac{22}{7}$

• $perimeter \: \: of \: \: circle \: = \: 2πr$

• $Area \: \: of \: \: circle \: = \: π{r}^{2} \: sq.\: unit.$
