Answer:
The volume of a sphere varies with the cube of the radius. Since the Earth is 3.67 times the moon's radius (6371/1736), it has 49.4 times the volume.

Answer:
b) a cylinder with diameter of 4
Step-by-step explanation:
the square is being rotated about the line m, the sides of the rectangle being cut by the line, have a total length of 4which would be the diameter of the cylinder
Answer:
9.76
Step-by-step explanation:
area of a rectangle = length * breadth
length = (2x + 3)
breadth = x
given area is 220 sq. inches.
thus,
220 = x * (2x+3)
220 = 2x² +3x
2x² + 3x -220 = 0
x = (-b + √ ( b²-4ac) ) ÷ 2a
x = ( -3 + √ ( 3² - 4*2*220) ) ÷ 2*2
x =9.76
