A sector with a radius of 8 cm has an area of 56pi cm2. What is the central angle measure of the sector in radians?

.

Step-by-step explanation:

Given information:

Radius of circle = 8 cm

Area of sector =

Formula for area of sector is

where, r is radius and is central angle in radian.

Substitute and r=8 in the above formula.

Therefore, the measure of the sector in radians is .

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
