Question

The perimeter of a circle is 88 mtr. Find the radius -
(a) 6 mtrs. (b) 10 mtrs. (c) 12 mtrs.​

Answer 1

Answer:

perimeter of a circle is called circumference.

so, circumference of circle = 2πr

88 = 2πr

88 = 2×22/7 ×r

r = 88 × 7/44 = 2×7 = 14 m

Answer 2

$\large\underline{\underline{\sf Given:}}$

• Perimeter of circle (C) = 88m

$\large\underline{\underline{\sf To\:Find:}}$

• Radius of Circle (R) = ?

$\large\underline{\underline{\sf Solution:}}$

We know that , perimeter of circle is also called as "Circumference"

•°•

$\large{\boxed{\sf Circumference\:of\:Circle(C)=2πr}}$

$\large\implies{\sf 88=2×\frac{22}{7}×r }$

$\large\implies{\sf r=\dfrac{88×7}{2×22} }$

$\large\implies{\sf r=\dfrac{616}{44}}$

$\large\implies{\sf r=14m }$

$\Large\underline{\underline{\sf Answer:}}$

•°•Radius of Circle is 14m.
