PLEASE HELP!! A circular sector has a central angle of π8 radians and a radius of 4 m.

What is the area of the sector?

Use 3.14 for pi. Round your answer to the nearest tenth.

Please show work if possible so that I can understand how you did it!

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
