Answer 1

Holla ^_^

☸ Required Answer is ⬇ ⬇⬇ ⬇

Given,

Diameter of garden roller = 1.4 m

Radius = 1.4/2 = 0.7 m

⭐ Circumference of garden roller = 2πr

= 2×3.14×0.7
= 4.396m

✨ Area covered by garden roller in 5 revolutions = 5 × 4.396
= 21.98m

Answer 2

$\huge{\underline{\sf{Question :-}}}}$

The diameter of a garden roller is 1.4 metre and it is to me know how much area will it cover in 5 revolutions

$\huge{\underline{\sf{Answer :-}}}}$

$\green{\underline\bold{Given,}}$

$\boxed{ \sf \orange{Diameter\:of\;the\; garden\:roller,\:D=\:1.4\:m}}$

$\boxed{ \sf \red{ To \: Find : }}$

✏ Area it will cover in 5 revolutions = ❓

$\green{\underline\bold{We \:know\:,}}$

✏ Radius, r = $\frac{Diameter}{2}$

✏ r = $\frac{1.4}{2}$

✏ r = 0.7 m

$\green{\underline\bold{From\:the\:formula,}}$

$\boxed{ \sf \blue{Circumference\: of\: the \:garden\: roller\: = \:2Πr }}$

= 2Πr

= 2 × $\frac{22}{7}$ × 0.7

= 4.396 m

$\green{\underline\bold{Now,}}$

$\boxed{ \sf \blue{ Area\: of \:the\: roller\: it\:will\:cover\: in\: 1 \:revolution=\:area\:of\:the\:roller }}$

= 4.386 m

$\boxed{ \sf \blue{ Area\: of \:the\: roller\: it\:will\:cover\: in\:5 \:revolutions= }}$

= 4.396 × 5

= 21.98 m

$\pink{\underline\bold{∴The\:required\:answer\:is\: = \:21.98\: m\: }}$
