The radius of the hemisphere is 9.5 inches.
The diameter of the hemisphere is 19 inches.
The surface area of the hemisphere is 850.2 inches²
<h3>How to find the surface area of an hemisphere?</h3>circumference of a circle = 2πr
where
- r = radius
Therefore,
19π = 2πr
2r = 19
r = 19 / 2
r = 9.5 inches
diameter = 9.5 × 2 = 19 inches
Therefore,
surface area of an hemisphere = 3πr²
surface area of an hemisphere = 3 × 3.14 × 9.5²
surface area of an hemisphere = 850.155 inches²
surface area of an hemisphere = 850.2 inches²

-1.42-2.9=1.48
1.424-(-2.9)=1.424+2.9=4.324
-1.424-(-2.9)-0.576=-1.424+2.9-0.576=3.748
I hope it helps!
