84+6=90
Ответ:
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
