## How many gallons are in a sphere?

One one-foot diameter sphere in volume and capacity sense converted to gallons liquid US equals precisely to 3.92 gal.

## How do you find the surface area and volume of a sphere?

Sphere Formulas in terms of radius r:

- Volume of a sphere: V = (4/3)πr.
- Circumference of a sphere: C = 2πr.
- Surface area of a sphere: A = 4πr.

**What is the volume of an 8mm sphere?**

267.95 cubic milli-meters

Hence, the volume of the sphere is 267.95 cubic milli-meters.

### How much volume is a sphere?

The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.

### What is the surface area of the sphere?

When we write the formula for the surface area of a sphere, we write the surface area of a sphere = 4πr2 = 4(πr2) = 4 × area of a circle.

**How do I calculate the volume of a pond?**

Use our handy calculator to work out your pond capacity.

- The easiest way to do this is to measure the length, the width and the depth of your pond in feet.
- Once you have all three dimensions, you need to multiply these all together and then multiply this calculation by 6.25.

## How do you calculate volume and surface area?

It gives the proportion of surface area per unit volume of the object (e.g., sphere, cylinder, etc.). Therefore, the formula to calculate surface area to volume ratio is: SA/VOL = surface area (x2) / volume (x3) SA/VOL = x-1 , where x is the unit of measurement.

## What is the volume of a hemisphere with a radius of 4.9 ft?

V = 246.403 m3 I’ll let you do the rounding.

**How to find the volume of a sphere?**

Surface area to volume ratio is also known as surface to volume ratio and denoted as sa÷vol, where sa is the surface area and vol is the volume. How to find the volume of a sphere? How to find the diameter of a sphere? How to find the radius of a sphere? How to find the area of the surface of a sphere?

### How to calculate the surface area of a hollow sphere?

If using this calculator to compute the surface area of a hollow sphere, subtract the surface area of the base. Given two values of height, cap radius, or base radius, the third value can be calculated using the equations provided on the Volume Calculator. The surface area equations are as follows:

### How is the surface area of a spherical cap calculated?

Spherical Cap. The surface area of a spherical cap is based on the height of the segment in question. The calculator provided assumes a solid sphere and includes the base of the cap in the calculation of surface area, where the total surface area is the sum of the area of the base and that of the lateral surface of the spherical cap.

**How to calculate the surface area of a cylinder?**

The surface area of a closed cylinder can be calculated by summing the total areas of its base and lateral surface: base SA = 2πr 2. lateral SA = 2πrh. total SA = 2πr(r + h) where r is radius and h is height. Jeremy has a large cylindrical fish tank that he bathes in because he doesn’t like showers or bath tubs.
