Answer:


Step-by-step explanation:
Given

Shape: Sphere
Solving (a): The Volume
This is calculated as:

Take
as 3.14 and substitute 14 for r





Solving (b): The Surface Area
This is calculated as follows:

Take
as 3.14 and substitute 14 for r



1. opposite sides are equivalent , opposite angles are equivalent
2. 4 sides, 4 angles, both answers for number one also work
3. A square
5x7=35 35/10=3.5
so 3.5 is the answer
Dont quote me on this but i think it is 10 because 86 × 2 is 172 and 297 ÷ 172 is 10 I think
