Answer:
22.05
Step-by-step explanation:
21x150%=31.5
31.5×30%=9.45
31.5-9.45=22.05
Compare two similar sides:
24:32 this reduces to 3:4
Answer: D) 3:4

Answer:
False
Step-by-step explanation:
we know that
To find the surface area of a three dimensional figure, you must find the area of each of its faces and then sum the areas
The surface area of a three dimensional figure is equal to the area of its bases plus the area of its lateral faces
