Question

Find the radius and Diameter of the circle give the
circumference, 32.5cm​

Answer 1

Answer:

Diameter = 10.833 cm

Radius = 5.4165 cm

Step-by-step explanation:

Diameter = circumfrence / 3

                = 32.5  /  3

                =  10.833 cm

Radius =  Diameter / 2

           =  10. 833 / 2

           =  5.4165  cm

Answer 2

Answer:

Radius of circle is 5.25 cm.

Diameter of circle is 10.5 cm .

Step-by-step explanation:

Given -

Circumference of circle is 32.5 cm

To find -

The radius and diameter of circle

Solution -

The circumference means the length of the complete arc of a circle.

As we know that,

Circumference of circle = $2 \times \pi \times r$

Where,

r is a radius of circle.

Put the given values in these formula we get

$32.5 = 2\pi \times r$

$\frac{32.5}{2\pi}  = r$

$\frac{16.25}{\pi}  = r$

The value of π is $\frac{22}{7}$ .

$\frac{16.25}{\frac{22}{7}}  = r$

$\frac{16.5 \times 7}{22} =r$

$\frac{115.5}{22} =r$

$r = 5.25$

So,

Radius of circle is 5.25 cm.

Diameter = radius × 2

Diameter = 5.25 × 2

Diameter = 10.5

Diameter of circle is 10.5 cm .
