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 volume of the ball in cubic meter with a radius of 7 cm V 4 3?
Well, the volume of a sphere is given by 4/3*pi*r^3. Setting r = 7, we get 4/3*pi*7^3 = 1436.75 ~= 1437 cm^3.
What is the area of a spherical balloon?
Therefore, the Surface Area of a Sphere with radius r equals 4πr2 .
What is the volume of this sphere 7cm?
Summary: The volume of the sphere with a radius of 7cm is 1437.33 cm3 and the volume of the sphere with a radius of 0.63m is 1.05 m³.
How do you find the area of a balloon?
How to Calculate the Volume and Surface Area
- Surface Area = 4 × π × r2
- = 4 × π × 52
- = 4 × π × 25.
- = 100 π
- ≈ 314.
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)
What is the value of a sphere of radius 7cm?
How big is a sphere shaped water balloon?
This quiz is incomplete! To play this quiz, please finish editing it. A spherical-shaped water balloon has a surface area of 113.04 square inches. How many cubic inches of water will the balloon hold?
Intuitively, this makes sense since the balloon’s volume is growing at a constant rate: as the balloon grows, a small change in the radius will have a larger impact on the change in volume; equivalently, the same change in volume corresponds to a smaller change in the radius when the balloon is large.
How big is a large sphere at an amusement park?
Q. A large sphere at an amusement park is 165 feet in diameter. Which of the following is closest to the volume, in cubic feet, of the sphere? Use π=3.14.
