Answer 1

Answer:

155.232

Step-by-step explanation:

18.48 multiply by 8.4

Answer 2

Answer:

The length of the arc is 4.4 units

Step-by-step explanation:

In a sector,

Area, A = 18.48 units

Radius, r = 8.4 units

To find: Length of the arc, l

Area of the sector,$A = \frac{l \times r}{2}$

$18.48 = \frac{l \times 8.4}{2}$

$l = \frac{18.48}{4.2}$

$l = 4.4 \: \: units$
