Answer:

B. 90

Step-by-step explanation:

[tex]\frac{a+b}{2} h=\frac{10+18}{2}*6= 84[/tex]

the trapezoid are is 84

[tex]\pi r^2= \pi 2^2=12.57\\[/tex]

there is half of the circle which is 6.285

84+6=90

Answer:

B. 90

Step-by-step explanation:

The formula for area of a trapezoid is A=(a+b/2)h

A=base ,10 (3 plus 4 plus 3)

B=base #2, 18 (10 plus 4 plus 4)

h=height, 6

plug into the formula and get

84

the formula for area of a circle is A=pi times r squared

The diameter of the semicircle is 4, so the radius has to be 2

plug into the formula and get

12.57

divide by two since there is only half of a circle

6.285

Add the area of the trapezoid and the semicircle

6.285+24= 90.28 or 90
