Q. A cylindrical glass has a volume of approximately 354 cm3. The glass has a diameter of 6 cm and is filled to 2 cm from the top with water. A golf ball 4 cm in diameter is placed into the glass. Complete the statements. The space remaining in the glass is ____ and the volume of the golf ball is ____. Therefore, putting the golf ball in the glass of water ____ cause the water to overflow.
Calculate Glass Volume: Calculate the volume of the cylindrical glass. The formula for the volume of a cylinder is V=πr2h, where r is the radius and h is the height. The diameter of the glass is given as 6 cm, so the radius r is half of that, which is 3 cm. The volume of the glass is given as 354 cm3. We can use this information to find the height of the glass.
Calculate Glass Height: Calculate the height of the glass using the volume.Using the volume formula V=πr2h, we rearrange it to solve for h: h=πr2V. We plug in the values we have: h=π⋅32354.h=π⋅9354h=28.274333882308138354 (using π≈3.141592653589793)h≈12.52 cm
Calculate Golf Ball Volume: Calculate the volume of the golf ball.The formula for the volume of a sphere (which is the shape of a golf ball) is V=34πr3. The diameter of the golf ball is given as 4 cm, so the radius r is half of that, which is 2 cm. We plug in the values to find the volume of the golf ball.V=34π×23V=34π×8V≈34×3.141592653589793×8V≈33.510321638291124 cm3
Calculate Remaining Space: Calculate the space remaining in the glass without the golf ball.Since the glass is filled to 2cm from the top with water, we subtract this from the total height of the glass to find the height of the water.Height of water = Total height of glass - Space from topHeight of water = 12.52cm−2cmHeight of water = 10.52cmNow we calculate the volume of the water using the height of the water.Volume of water = πr2× Height of waterVolume of water = π×32×10.52Volume of water ≈3.141592653589793×9×10.52Volume of water ≈295.305144033386cm3
Calculate Remaining Space After Golf Ball: Calculate the space remaining in the glass after the golf ball is placed in it.We subtract the volume of the golf ball from the space remaining in the glass to see if there is enough space for the golf ball without causing the water to overflow.Space remaining in glass = Volume of glass - Volume of waterSpace remaining in glass = 354cm3−295.305144033386cm3Space remaining in glass ≈58.694855966614cm3Now we compare this with the volume of the golf ball.Space remaining after golf ball is placed = Space remaining in glass - Volume of golf ballSpace remaining after golf ball is placed ≈58.694855966614cm3−33.510321638291124cm3Space remaining after golf ball is placed ≈25.184534328322876cm3
Determine Water Overflow: Determine if the water will overflow.If the space remaining after the golf ball is placed is positive, the water will not overflow. If it is negative, the water will overflow.Since we have a positive value for the space remaining after the golf ball is placed, the water will not overflow.
