In a circle with a radius of 8 ft, an arc is intercepted by a central angle of 3π4 radians.

what is the length of the arc?

The arc length  is, 18.84 ft.

Step-by-step explanation:

Length of an arc is given by:

             .....[1]

where r is the radius of the circle and is the angle in radian.

As per the statement:

In a circle with a radius of 21 5/8 yd, an arc is intercepted by a central angle of radians

⇒r = 8 ft

and radian

Substitute these values in [1] we have;

ft.

therefore, the arc length  is, 18.84 ft.

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
