First you add 3/4 and 2/3 you but then do 3/4 2/3 you think what the both can go to is 12 the dominator is 12 then you time it by 3,4 because they both go to 12 then the 3 will be time 3 because 4 x 3 = 12 then you do it the top so 3x3 = 9 9/12 then you do the next one is2/3 do the same then will get 8/12 then you can subtract it 9/12 - 8/12 will gave you 1/12

Answer:
6.28
Step-by-step explanation:
Find the diameter by multiplying the radius by 2, then multiply the diameter by Pi, which in your case is 3.14
R times 2= diameter
D time Pi= area
Area = 6.28

It's 56 and 72 because 56/8=7 and 72/8=9
        
                    
             
        
        
        
First way: m+7m+m+7m
Second way: m(1+7+1+7) (factorize)
Third way: 2(m)+2(7m)
