The formula given below calculates the lateral surface area of a dome by multiplying the radius of the base, the height of the dome, and the constant π\piπ, then multiplying by 2. This gives the area of the curved surface of the dome.

Formula:

The formula is:

\text{DSA} = 2 \times \pi \times r \times h

Variables:

Variable	Meaning
DSA	Dome Surface Area
$\pi$	Mathematical constant (approximately 3.14159)
$r$	Radius of the base of the dome
$h$	Height of the dome

Solved Examples:

Example 1:

Given:

Radius ( $r$ ) = 5 meters
Height ( $h$ ) = 10 meters

Calculation	Instructions
Step 1: DSA = $2 \times \pi \times r \times h$	Start with the formula.
Step 2: DSA = $2 \times 3.14159 \times 5 \times 10$	Replace with 5 meters and $h$ with 10 meters.
Step 3: DSA = $2 \times 3.14159 \times 50$	Multiply $r \times h$ to get 50.
Step 4: DSA = $2 \times 157.0795$	Multiply by $\pi$ to get 157.0795.
Step 5: DSA = 314.159 square meters	Multiply by 2 to get the surface area.

Example 2:

Given:

Radius ( $r$ ) = 3 meters
Height () = 7 meters

Calculation	Instructions
Step 1: DSA = $2 \times \pi \times r \times h$	Start with the formula.
Step 2: DSA = $2 \times 3.14159 \times 3 \times 7$	Replace $r$ with 3 meters and with 7 meters.
Step 3: DSA = $2 \times 3.14159 \times 21$	Multiply $r \times h$ to get 21.
Step 4: DSA = $2 \times 65.9734$	Multiply by $\pi$ to get 65.9734.
Step 5: DSA = 131.9468 square meters	Multiply by 2 to get the surface area.

Answer: The surface area of the dome is 131.9468 square meters.
