Find the area of the circle whose diameter is 12 cm
FORMULA
- [tex]{ \rm{→ A = \frac{π {d}^{2} }{4} }} \\ [/tex]
SOLUTION
[tex]{ \rm{ A = \frac{π {d}^{2} }{4} }} \\ { \rm{ A = \frac{(3.14){(12)}^{2} }{4} }} \\ { \rm{A = \frac{(3.14) (144)}{4} }} \\ { \rm{ A = \frac{ 452.16}{4} }} \\ { \color{pink}{ \boxed{ \large{ \pink{\rm{ A = 113.04 \: {cm}^{2} }}}}}} \\ [/tex]
ANSWER
The area of the circle whose diameter is 12 cm is 113.04 cm²
