Find the volume of the solid generated by revolving the region between the curve y = sinxxcosx and the line y = 1 for the interval given [0, pi/2]

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

a)(x-2)^2+(y-1)^2=9
