Answer:
301.44
Step-by-step explanation:
V = h x π x r^2 
V = 6 x 3.14 x 4^2 
V = 301.44

Answer:  21.994 cm²
Step-by-step explanation:
 Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.
 Formula for finding area of a circle       =  πr² where π is a constants . It has value of         22/7 or 3.142
 Now area of the bigger circle                = 3.142 x 3²
                                                                   = 3.142 x 9
                                                                   = 28.278 cm²                                       Now are of the two smaller triangle        = 3.142 x 1² x 2
                                                                    = 6.284 cm².
Therefore are of the shaded region        = 28.278 - 6.284
                                                                    = 21.994 cm²
 
        
             
        
        
        
B) Parallelogram JKLM is translated and then dilated
as well as c
C) Parallelogram JKLM is dilated and translated
C is the best answer because is size is changing. In all the others nothing is changing except the position which remains congruent and similar but C does not . The sizes changes which makes them not congruent but still similar.

r = 7.53 so d = 2r = 2(7.53) = 15.06 cm
Area of square = d^2 / 2 = (15.06)^2 / 2 = 113.41 cm^2
Area of circle = 3.14 (7.53)^2 = 178.04 cm^2
Area of yellow region = Area of circle - Area of square
Area of yellow region = 178.04 cm^2 - 113.41 cm^2
Area of yellow region =64.63 cm^2 = 64.6 cm^2 (nearest tenth)
Answer
64.6 cm^2
