Answer:
Step-by-step explanation:
<h3>
Sphere:</h3>
1) a) r = 7 cm



= 4*3.14 * 7 * 7
= 615.44 cm²
b) r= 8.4 cm


Surface area = 4*3.14*8.4*8.4
= 887.04 cm²
<h3>Hemisphere:</h3>
a) r = 6 cm




= 3 * 3.14 * 6 * 6
= 339.12 cm²
For example:
L plus W
3 plus 6= 9
I plus W
4 plus 6= 10
total: 9+10= 19
(this is just an example)
