Hey ! there

Answer:

Explanation:

In this question we are provided with a circle having diameter 10 yd . And we are asked to find the circumference of circle .

For finding circumference of circle , we need to know the formula for finding circumference . So ,

$\qquad \quad \underline{\boxed{\frak{Circumference{(Circle)} = 2\pi r}}}$

Where ,

Solution : -

After reading question we get to know that we aren't provided with radius . So finding radius :

Now , finding circumference :

$\quad \: \longmapsto \qquad \:2 * 3.14 * 5$

Multiplying 2 with 3.14 :

$\quad \:\longmapsto \qquad \:6.28 * 5$

Multiplying 6.28 with 5 :

$\quad \: \longmapsto \qquad \: \orange{\underline{\boxed{\frak{31.4 \: yards}}}} \quad \bigstar$

Henceforth , circumference of circle having diameter 10 yards is 31.4 yards.

Answer:

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Circumference of a circle is given by

$C = 2\pi \: r$

$radius = (diameter)/(2) = (10)/(2) \\ \\ \implies \: 5 \: yards$

now ,

substituting the value of r in the formula of circumference ~

$C = 2 * (22)/(7) * 5 \\ \\ \implies \: C = (220)/(7) \\ \\ \implies \: C = 31.43 \: yards \: (approx.)$

hope helpful :D
