Question

um of the radll of the circumcircle and incircle of an equilateral Tangle
13. What is the approximate sum of the radii of the
of side v3 units?
(a) 1.5 units
(c) 2.5 units
(b) 2 units
(d) 3 units​

Answer 1

Answer:

Option (a) 1.5 units

Step-by-step explanation:

$radius \: of \: incircle \: of \: equilateral \: triangle \: \\ = \frac{(s)side \: of \: equilateral \: triangle}{3} \\ = \frac{ \sqrt{3} }{3} \\ = \frac{1}{2}$

$radius \: of \: circumcircle \\ = \frac{side}{ \sqrt{3} } \\ = \frac{ \sqrt{3} }{ \sqrt{3} } \\ = 1$

The approximate sum of the radii is 1/2+1

=1.5 units
