The base of a solid is the region between the curve yequals3 cosine x and the ​x-axis from xequals0 to x equals StartFraction pi
xz_007 [3.2K]

Answer:

A=3(π/2)-1 au

Step-by-step explanation:

we have according to the graph that

f(x)=3

g(x)=cos(x)

Knowing A=∫|f(x)-g(x)|dx, then

A=\int\limits^a_b (f(x)-g(x)}) \, dx\\; where a=0 and b=π/2

A=\int\limits^a_b (3-cos(x)){} \, dx

A=(3x-sin(x)) evaluated  0 ≤ x ≤ π/2

A=(3(π/2)-sin(π/2))-(3.0-sin(0))

A=3\frac{\pi }{2}-1
