Question

Find the radius of a circlar tent is 7m. Find the circumference of the base of the tent.

Answer 1

Given:

• Radius of circular tent (r) = 7m.

To Find:

• Circumference of circular tent = ?

Formula Used:

• Circumference of circle = 2πr.

Solution:

Substituting values,

➺ 2 × 22/7 × 7

➺ 2 × 3.14 × 7

➺ 6.28 × 7

➺ 43.96

➛ 44cm. (Approx)

Thus,

• Circumference of circular tent is 44cm.

ExtraShots:

• Area of circle = πr².

• Circumference of circle = 2πr.

• Diameter of circle = 2 × r.

• Area of sector = length of arc × radius / 2.

• Length of arc = θ/360 × 2πr.

• Area of segment = r² (θπ/360 - sinθ/2).

Answer 2

$\Large{\underline{\underline{\sf{Answer:}}}}$

$\huge{\boxed{\sf{\red{44m}}}}$

$\Large{\underline{\underline{\sf{Step\:by\:step\:explanation:}}}}$

Given that,

the radius of a circlar tent is 7m.

We need to find the circumference of the base of the tent.

Acknowledgement —

$\large{\star}{\boxed{\sf{\orange{Circumference=2\pi r}}}}{\star}$

Substitute the values, we get

:$\implies{\sf{2 \times \dfrac{22}{7} \times 7}}$

:$\implies{\sf{2 \times \dfrac{22}{ \cancel{7}} \times \cancel{7}}}$

:$\implies{\sf{2 \times 22}}$

:$\implies{\sf{2 \times 22}}$

:$\large\implies{\boxed{\sf{\red{44m}}}}$

Hence, the circumference of the base of circular tent is 44m.

And we are done! :D

➤ What is circle?

➛ a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the centre).

______________________

The Radius is the distance from the center outwards.

The Diameter goes straight across the circle, through the center.

$\large{\boxed{\sf{Diameter=2r}}}$

The Circumference is the distance once around the circle.

$\large{\boxed{\sf{Circumference=2\pi r}}}$

The Area is the area enclosed by the circle.The area of a circle is π times the radius squared, which is written:

$\large{\boxed{\sf{Area=\pi r^{2}}}}$
