How do you find the volume of a spherical balloon?
The formula for the volume of a sphere is V = 4/3 πr³.
What is the area of a spherical balloon?
Therefore, the Surface Area of a Sphere with radius r equals 4πr2 .
How do you find the diameter of a sphere?
The diameter of a sphere can be found with the following equations:
- With given radius: d = 2 * r ,
- With given diameter: d = √(A / π) ,
- With given volume: d = ³√(6 * V / π) .
How many cubic feet is a sphere?
For a Sphere For example, if your radius is 3 feet, then the radius to the third power is 27 cubic feet. Multiply the result of step 1 by pi, which is a constant that approximately equals 3.14. Using the example from step 1, multiplying 27cubic feet by 3.14 is 84.78 cubic feet.
How do you find the SA of a sphere?
The steps to calculate the surface area of a sphere is:
- Step 1: Know the radius of the sphere.
- Step 2: Take the square of the radius by multiplying it by itself.
- Step 3: Multiply r2 by 4.
- Step 4: Multiply the value of 4r2 by the approximate value of pi, that is, 3.14.
- Step 5: At last, add the units to the final answer.
What is the volume of a balloon?
| Round Latex Balloons | ||
|---|---|---|
| Balloon Size | Approximate Volume | Approximate Lift |
| 36 inches | 14.134 cu. ft. | 11.872 ounces |
| 40 inches | 19.388 cu. ft. | 1 pound .286 ounces |
| 4 feet | 33.502 cu. ft. | 1 pound 12.142 ounces |
How do you find the diameter in inches?
Divide the circumference by pi, approximately 3.14, to calculate the diameter of the circle. For example, if the circumference equals 56.52 inches, divide 56.52 by 3.14 to get a diameter of 18 inches. Multiply the radius by 2 to find the diameter.
How do you find the diameter?
How To Calculate Diameter?
- Diameter = Circumference ÷ π (when the circumference is given)
- Diameter = 2 × Radius (when the radius is given)
- Diameter = 2√[Area/π] (when the area is given)
How do you find the volume of a ball with the diameter?
FAQs on Diameter of a Sphere Formula Using Volume The volume of a sphere (V) in terms of its radius (r) is V = (4/3) π r3. If d is its diameter, we have d = 2r. From this, we get r = (d/2). Substituting this in the volume formula, the volume of a sphere in terms of diameter is V = (πd3)/6.
What is the diameter of a balloon?
The size of the round balloon (for example, 5 inches) is actually the diameter of the balloon when it is almost fully inflated. By the way, the most common size of round balloons (with which we often create balloon designs for events with) is 12 or 11 inches.
How big is the volume of air in a balloon?
Simplify. So, the volume of air in the balloon is about 1,436 feet. Air is leaking from the balloon at the rate of 26 cubic feet per minute. To know how long it would take for the balloon to empty 1,426 cubic feet of air, divide 1,426 by 26.
How much does the quality of a balloon vary?
You’ll find it here! Note: Balloon quality may vary as much as 20% depending on how tightly the balloon clusters are packed. Note: The listed average inflation sizes and flying times are conservative averages.
How big is the volume of a soccer ball?
So, the volume of the soccer ball is about 7,234.6 cubic cm. Jose measures the diameter of a ball as 14 inches. How many cubic inches of air can the ball hold, to the nearest tenth?
How long does it take for a balloon to empty?
Air is leaking from the balloon at the rate of 26 cubic feet per minute. To know how long it would take for the balloon to empty 1,426 cubic feet of air, divide 1,426 by 26. So, it would take about 55 minutes for the balloon to empty fully.
