What is the area of the composite figure?
a (8π + 6) in.2
b (8π + 12) in.2
c (8π + 18) in.2
d (8π + 24) in.2

ANSWER

The correct option is B

EXPLANATION

The composite figure is made up of a semicircle and an isosceles triangle.

The area of a semicircle is

From the diagram, the radius is

When we substitute, area of the semicircle is

The area of the isosceles triangle is

We add the two areas to obtain the area of the composite figure to be:

20

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
