Masteriza [31]

Answer:

Step-by-step explanation:

Distance between earth and moon in meters = 386400 x 10³ m

Speed of ship = 11184.7258 m / s

Time taken = distance of moon from earth / speed of ship

= 386400 x 10³ / 11184.7258

= 34.5471 x 10³ s

= 34.5471 x 10³ / 60 x 60 hour

The base of a 6-inch long ice cream cone with a diameter of 2 inches, is cut 0.25 inches from the base. This cut creates two sha
Tamiku [17]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Length of ice cream cone = 6 inch

Diameter of cone = 2 inches

Radius of cone is given by

\frac{2}{2}=1\ in.

But according to question, it is cut 0.25 inches from the base  and this cut into cylinder and cone.

Since it was cut so close to the base.

So, Height of the cylinder = 0.25 inches

As we know the  formula for "Volume of cylinder ":

Volume=\pi r^2h\\\\Volume=\frac{22}{7}\times 1\times 1\times 0.25\\\\Volume=0.785\ in^3\\\\Volume=0.79\ in^3

Hence, Option 'C' is correct.
