Answer: 308cm
Step-by-step explanation: The formula to find the curved surface area of a cylinder is 2πr × h. The formula for curcufrence is 2πr.
So,
2πr (circumfrence)= 44cm.
Height= 7cm.
2πr × h = 44 x 7 = Curved surface area.
Curved surface area= 308cm
45 yard = 1215 cubic feet
Based on that, i think the answer is : C. The Volume of the prisms stays the same, but the number representing the volume increases
Yard and feet are only unit of measurement. Changing this does not affect the actual volume
hope this helps
Answer:
12 cm²
Step-by-step explanation:
Use the area formula A = lw, where l is the length and w is the width:
A = lw
A = (3)(4)
A = 12
= 12 cm²
