15
<p>The formula considers both the curved surface area and the<a>base</a>area of the hemisphere.</p>
17
<p>Surface Area = 2πr² (curved surface) + πr² (base) = 3πr²</p>
16
<p>Surface Area = 2πr² (curved surface) + πr² (base) = 3πr²</p>
18
<p>Therefore, the formula is: Surface Area = 3πr² By applying this formula, we can determine the total surface area of a hemisphere with a given radius.</p>
