The surface area of the hemisphere with radius r = 19 cm. is 3400.62 square centimeters
<h3>How to determine the surface area?</h3>
The radius is given as:
r = 19
The surface area of a hemisphere is:
Area = 3πr²
So, we have:
Area = 3 * 3.14 * 19²
Evaluate
Area = 3400.62
Hence, the surface area of the hemisphere is 3400.62 square centimeters

It would round up to 3.620
:)
2.because
5.50x4=22
2.25x2=4.50
that will equal 26.50 but when you add the money she already had saved up which is 5.25
you will get 31.75
C because twice the difference of a number and 5
2 (n-5)
or it can be wrtten as 2(x-5)
