Answer 1

Answer :

(1) The radius of a circle is 1.5 m.

(2) The diameter of a circle is 28 ft.

(3) The radius of a circle is 10 in.

(4) The circumference of circle is 47.14 m.

(5) The circumference of circle is 44 yd.

Step-by-step explanation :

Part 1:

Given: d = 3 m

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = $\frac{Diameter}{2}$

So,

Radius of a circle = $\frac{3m}{2}=1.5m$

The radius of a circle is 1.5 m.

Part 2:

Given: r = 14 ft

Now we have to determine the diameter of circle.

As we know that:

Radius of a circle = $\frac{Diameter}{2}$

So,

Diameter of a circle = $Radius\times 2$

Diameter of a circle = $14ft\times 2=28ft$

The diameter of a circle is 28 ft.

Part 3:

Given: d = 20 in

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = $\frac{Diameter}{2}$

So,

Radius of a circle = $\frac{20in}{2}=10in$

The radius of a circle is 10 in.

Part 4:

Given: d = 15 m

Now we have to determine the circumference of circle.

Formula used:

$C=\pi d$

where,

C = circumference

d = diameter

So,

$C=\frac{22}{7}\times 15m$

$C=47.14m$

The circumference of circle is 47.14 m.

Part 5:

Given: r = 7 yd

Now we have to determine the circumference of circle.

Formula used:

$C=\pi d$

or we can write,

$C=\pi (2\times r)$

where,

C = circumference

d = diameter

r = radius

So,

$C=\frac{22}{7}\times (2\times 7yd)$

$C=44yd$

The circumference of circle is 44 yd.
