Circumference of a ○ = πr2h

Answer 2

Find the circumference of ⊙C . Round your answer to the nearest hundredth.

The circumference is about ............. meters.

Answer:

The required answer is $e=35.52 \mathrm{~m}$.

Step-by-step explanation:

Circumference: The distance around something round or rounded, particularly the distance around the edge of a circle, is referred to as its circumference. The distance around a circle's circumference serves as an illustration of circumference.

Given: the arc $F_{n}$ $=7.5 \mathrm{~m}$ and Angle= $76^{\circ}$

To Find- the circumference of ⊙C.

Solution-

The circumference formula

$c=2 \pi r$

The formula of arc length is

$r &=\frac{\theta}{360^{\circ}} \times 2 \pi r$

Substitute values and Calculate circumference.

$\Rightarrow \quad 7 \cdot 5 &=\frac{76^{\circ}}{360^{\circ}} \times C$

$\Rightarrow \quad 7.5 &=\frac{19}{90} \times C$

$\Rightarrow \quad C &=\frac{75 \times 90}{19}$

Therefore, $\quad C &=35.52 \mathrm{~m}$

Hence, the circumference of ⊙C is $e=36.52 \mathrm{~m}$.
