Answer 2

Answer:

Question

✳️The circumference of a circular disc is 88 cm , it's radius is

Solution ⬇️

✍️We know that

✍️ Circumstances of a circle =2πr

$= > 88 = 2 \times \frac{22}{7} \times r \\ = > r = \frac{88 \times 7}{2 \times 22} \\ = > r = \frac{8 \times 7}{2 \times 2} \\ = > r = \frac{4 \times 7}{2}$

$= > r = 2 \times 7 \\ => 14cm$

✍️ Therefore, radius of a cuboid=14cm
