The surface area of the given shape shown in the question is 254.34 in²
How to calculate the surface area of the shape?
A careful observation of the shape shown in the question above shows that the shape is a circle.
The surface area of a circle is given by the following formula:
A = πr²
Where
- A is the surface area of the circle
- r is the radius of the circle
With the above formula, we shall calculate the surface area of the circle. This is shown below:
- Radius of circle (r) = 9 in
- Pi (π) = 3.14
- Surface area of circle (A) =?
Surface area of circle (A) = πr²
Input the the value of π and r to obtain the area:
= 3.14 × 9²
= 3.14 × 81
= 254.34 in²
