Question

Find radius of circle whose circumference is 8.8cm.us of circle whose circumference is 8.8cmradi

Answer 1

Hey mate the4e is yoir answer,
circumference of circle is given =8.8cm
2×pi×r= 8.8
2×22 r = 8.8×7
r = 61.6/ 44
r = 1.4 cm
so the radius of the circle is 1.4cm.
I hpe it's help you
plz mark me as brainliest.

★ Solution :

$\\ \:\:$

Circumference of circle = 8.8cm

⇒ 2πr = 8.8cm

⇒ 2 × 22/7 × r = 8.8cm

⇒ 44/7 × r = 8.8cm

⇒ r = 8.8cm × 7/44

⇒ r = 0.2cm × 7

⇒ r = 1.4 cm × 7
