I need to know how long arc BC is

Arc length of arc BC is 6.98 units or roughly 7  units.

Step-by-step explanation:

First recall that the formula for the circumference of a circle is C = 2πr, where r is the radius.  Here the radius is 4 units. so the circumference of the (entire) circle is C = 2π(4 units) = 8π units.

The central angle for the arc shown in yellow is 100 degrees.  The length of this arc is a fraction of C as found earlier:

100

* 8π units = 800π/360 units, or 6.98 units (about 7 units).

360

Arc length of arc BC is 6.98 units or roughly 7  units.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
