Question

The diameter of a circular garden is 9.8 m. Its area is known.​

Answer 1

radius=diameter/2m

=9.8/2m

=4.6m

area of circle=πr^2

=22/7x(4.6)^2

=66.44m^2

answer is 66.44m^2

Answer 2

◇Question

diameter of a circular garden is 9.8 m.find its area..

◇Step to step explanation:

$\sf \red{diameter = 9.8m}$

◇formula:

$\bf{ \boxed{ \green{ \tt{radius = r = \frac{diameter}{2} \: }}}}$

》$\sf \red{ \frac{9.8}{2}}$

》$\sf \red{ \frac{98}{20}}$

》$\sf \red{ \frac{49}{10}}m$

☆other formula

$\bf{ \boxed{ \underline{ \blue {\tt{area \: of \: circle = \pi {r}^{2} \: }}}}}$

》$\rm{ \frac{22}{7} \times ( \frac{49}{10}) }^{2}$

》$\rm{ \frac{22}{7} \times \frac{49}{10} \times \frac{49}{10}}$

》$\rm{ \frac{22}{1} \times \frac{7}{10} \times \frac{49}{10}}$

》$\rm{ \frac{154 \times 49}{100}}$

》$\rm{ \frac{7546}{100}}$

》$\rm{75.46 {m}^{2}}$

i hope its help uh
