Question

find the area of the circle which the radius is 7/4

Answer 1

Answer:

Area of circle = pie * r2

= 22/7 * 7/4*7/4

= 9.62

Step-by-step explanation:

Answer 2

${\large{\mathfrak{\underline{\underline{Solution :}}}}}$

$\sf{Radius\:of\:circle\:=\: {\dfrac{7}{4}} \ units}$

${\boxed{\sf{Area \ of \ circle \ = \ \pi r^2}}}$

$\sf{Area \ = \ {\dfrac{22}{7}} × ({\dfrac{7}{2}})^2}$

$\sf{Area \ = \ {\dfrac{22}{7}} × {\dfrac{49}{16}}}$

$\sf{Area \ = \ 9.625 \ unit^2}$
