a) 6.4cm
b)7.4cm
c) 8.4cm​

Answer 1

Answer:

(b) 7.4 cm

because diameter=2×r

=3.7*2

=7.4 cm

Answer 2

$\huge \underline{ \underline{ \pink{ \purple✯ \: Aɴsᴡᴇʀ \: \purple{ ✯}}}}$

we know that,

• the longest chord of the circle is diameter of that circle

and

$\bold{diameter = 2 \times radius} \\ \\ \implies \bold{3.7 \times 2} \\ \\ \implies \bold{7.4 \: cm} \:$

so, length of the longest chord of the circle is 7.4 cm

hence, option (b) is correct
