About 90ft 
step-by-step explanation: 1/2 (a+b) x h is area of trapezoid. So that would be 40 
then area of circle is pi x radius squared. So that is 50.24 roughly.
so 50+40=90 
and yeah
hope this helped :))

Step-by-step explanation:
 
        
             
        
        
        
First, the dot stands for the "product". You have to multiply.
5/8* 2/7
= [5/ (2*4)]* (2/7)
= 5/4* 1/7 (because 2 and 2 cancel out)
= (5*1)/ (4*7)
= 5/28
The final answer is 5/28~
