What is the area of the composite figure?

500
490.62
245.31
745.31

ANSWER

745.31

EXPLANATION

The composite figure is made up of a rectangle and a semicircle.

The area of the rectangular portion

is

The semicircle has a radius of

r=12.5cm

The area of the semicircular portion is

Substitute the value of r and π=3.14 to obtain,

We add the two areas to obtain, the area of the composite figure.

500+245.3125=745.31 cm² to the nearest hundredth.

answer: b

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
