$\large \: \fcolorbox{grey}{black}{\bf \: \: \: \: \: \: \: \: \: \: AREA OF CIRCLE \: \: \: \: \: \: \: \: }$

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

$\large \: \fcolorbox{grey}{black}{\bf \: \: \: \: \: \: \: \: \: \: CIRCUMFERENCE \: \: \: \: \: \: \: \: }$

$\qquad \qquad \boxed{\displaystyle\sf Circumference = 2πr}$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\qquad \qquad \qquad \large \: \fcolorbox{grey}{black}{\bf GIVEN }$

⇏ π = 3.14 or 22/7

⇏ Area = πr² = 75.46m2

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\qquad \qquad \qquad \large \: \fcolorbox{grey}{black}{\bf TO FIND: }$

$\red{ \longmapsto\:}$ Radius

$\red{ \longmapsto\:}$ Circumference

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\qquad \large \: \fcolorbox{grey}{black}{\bf RADIUS OF CIRCLE }$

$\begin{gathered}\displaystyle\sf :\implies \pi r^{2} = 75.46m²\end{gathered}$

$\begin{gathered}\displaystyle\sf :\implies r^{2} = \frac{75.46m²}{\pi} \end{gathered}$

$\red{ \longmapsto\:}$ Taking π as 3.14,

$\begin{gathered}\displaystyle\sf :\implies r^{2} = \frac{75.46m²}{3.14} \end{gathered}$

$\begin{gathered}\displaystyle\sf :\implies r^{2} = 24.0318471337.. \end{gathered}$

$\begin{gathered}\displaystyle\sf :\implies r = \sqrt{24.0318471337..} \end{gathered}$

$\begin{gathered}\displaystyle\sf :\implies r = 4.9 \end{gathered}$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\qquad \large \: \fcolorbox{grey}{black}{\bf CIRCUMFERENCE }$

$\begin{gathered}\displaystyle\sf :\implies 2\pi r = 2 \times 3.14 \times 4.9\end{gathered}$

$\begin{gathered}\displaystyle\sf :\implies 2 \times 3.14 \times 4.9 = 30.772\end{gathered}$

Answer 2

Answer:

Photosynthesis definition states that the process exclusively takes place in the chloroplasts through photosynthetic pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll. All green plants and a few other autotrophic organisms utilize photosynthesis to synthesize nutrients by using carbon dioxide, water and sunlight. The by-product of the photosynthesis process is oxygen.Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
