Answer 1

Answer:

15.70

Step-by-step explanation:

2×3.14×10(90÷360)=15.70

Answer 2

Answer

The length of the arc is 15,7 km

Explain

Form :

$=2 \times \pi \times {r} \times \frac{ \alpha \degree}{360 \degree}$

.

Solve :

$= 2 \times \pi \times r \times \frac{ \alpha \degree}{360 \degree}$

$= 2 \times 3.14 \times 10 \times \frac{90}{360}$

$= 2 \times 31.4 \times 1 \times \frac{ \cancel{90}}{ \cancel{360}}$

$= \cancel2 \times 31.4 \times \frac{1}{ \cancel4}$

$= 31.4 \times \frac{1}{2}$

$= \frac{31.4}{2}$

$= 15.7 \: km$
