Question

Tick the correct answer in the following and
justify your choice: If the perimeter and the
area of a circle are numerically equal, then the
radius of the circle is
(A) 2 units
(B) π units
(C) 4 units
(D) 7 units​

Answer 1

Step-by-step explanation:

$\huge\mathfrak\red{Answer!!}$

answer is ᴏᴘᴛɪᴏɴ (ᴀ)

$( \: numerical \: area \: of \: the \: circle)$

$= (numerical \: circumference \: of \: the \: circle)$

$\pi {r}^{2} = 2\pi \: r$

$\pi {r}^{2} - 2\pi \: r = 0$

${r}^{2} - 2r = 0$

$r(r - 2) = 0$

$r = 0 \: or \: r = 2$

$but \: r \: cannot \: be \: zero$

$r = 2 \: units$

$thus \: the \: radius \: of \: circle \: is \: 2 \: units....$

Answer 2

Answer:

A/Q

2π r = π r²

2π = π r

2π/π = r

r = 2 ans.
