Answer 1

Answer:

$\huge\blue{\boxed{\red{\mathfrak{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\blue{✯answer✯}}}}}}}}}$

The Circumference of a Circle = 2πr

ATS,

\begin{gathered}2\pi r = 66 \\ \\ r = \frac{66}{2 \times \frac{22}{7} } \\ \\ = \frac {66 \times 7}{2 \times 22} \\ \\ = \frac{3 \times 7}{2} \\ \\ = \frac{21}{2} \end{gathered}

2πr=66

r=

21

. °. Diameter of the garden

2r = 2 × 21/2

2r = 21

Hence, Diameter of the garden is 21 m

Answer 2

$\huge \fcolorbox{yellow}{red}{Solution࿐}$

The Circumference of a Circle = 2πr

ATS,

$2\pi r = 66 \\ \\ r = \frac{66}{2 \times \frac{22}{7} } \\ \\ = \frac {66 \times 7}{2 \times 22} \\ \\ = \frac{3 \times 7}{2} \\ \\ = \frac{21}{2}$

. °. Diameter of the garden

2r = 2 × 21/2

2r = 21

Hence, Diameter of the garden is 21 m.
