Question

if the circumference of the circle is 88 cm find its radius and diameter.​

Answer 1

Step-by-step explanation:

2πr = 88

2 × 22/7 × r = 88

44/7 × r = 88

r = 14 cm

Diameter = 2r

=> 14 × 2

=> D = 28 cm

Answer 2

Answer:

Radius = 14cm

Diameter = 28cm.

Step-by-step explanation:

We know that,

$circumference \: of \: circle = 2\pi \: r$

Where, r is the radius of the circle.

On substituting the given values, we have,

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

$\frac{44}{7} \times r = 88$

$\frac{r}{7} = 2$

$r = 2 \times 7$

$r = 14cm$

We know that,

$diameter(d) \: = 2r$

On substituting r value, we have,

$d = 2 \times 14$

$d = 28cm$

Therefore, the radius and diameter of the circle are 14cm and 28cm respectively.

Hope it helps you.

Good Luck.
