Variables

Variable	Meaning
A	Surface Area of the capsule
$r$	Radius of the spherical ends of the capsule
$h$	Height (or length) of the cylindrical part of the capsule

Solved Examples:

Example 1:

Given:

Radius () = 3 cm
Height () = 10 cm

Calculation	Instructions
Step 1: $A = 4\pi r^2 + 2\pi rh$	Start with the formula.
Step 2: $A = 4\pi (3)^2 + 2\pi (3)(10)$	Replace $r$ with 3 cm and $h$ with 10 cm.
Step 3: $A = 4\pi (9) + 2\pi (30)$	Calculate $r^2 = 9$ and multiply $r \times h = 30$
Step 4: $A = 36\pi + 60\pi$	Multiply $4 \times 9 = 36$ and $2 \times 30 = 60$
Step 5: $A = 96\pi$	Add the two terms.
Step 6: $A \approx 301.59 \, \text{cm}^2$	Multiply by $\pi \approx 3.14159$ to get the surface area.

Step 3: $A = 4\pi (25) + 2\pi (40)$	Calculate $r^2 = 25$ and multiply $r \times h = 40$
Step 4: $A = 100\pi + 80\pi$	Multiply $4 \times 25 = 100$ and $2 \times 40 = 80$
Step 5: $A = 180\pi$	Add the two terms.
Step 6: $A \approx 565.49 \, \text{cm}^2$	Multiply by $\pi \approx 3.14159$ to get the surface area.

Answer: The surface area of the capsule is approximately 565.49 cm².

What is Capsule Surface Area Calculator ?

The Capsule Surface Area Calculator used to calculate the total surface area of a capsule-shaped object. A capsule is a geometric shape that consists of a cylinder with hemispherical ends on both sides. The surface area of the capsule is made up of the surface area of the cylindrical part and the surface areas of the two hemispherical ends.

The formula $A = 4\pi r^2 + 2\pi rh$ calculates this total surface area by adding the surface area of the two hemispheres (which together form a full sphere) and the surface area of the cylindrical part.
