Answer: 7cm
Explanation:
The surface area of a sphere is calculated by using the formula:
A = 4πr²
Since the surface area is 616cm², using the formula given, the radius will be calculated thus:
A = 4πr²
616 = 4 × 22/7 × r²
616 = 88/7 × r²
Multiply both side by 7/88
616 × 7/88 = 88/7 × 7/88 × r²
49 = r²
r = ✓49
r = 7
The radius is 7cm

Explanation:
Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made.
What is the evaluation process?
The whole measurement/evaluation process is a six-stage, cyclic affair, involving:
The selection of characteristics to be measured
The selection of a suitable method of measuring
The collection of that data
The analysis of the collected data
The making of decisions
The implementation of those decisions
All of the above stages should be completed with the athlete - especially the analysis of the collected data and deciding an appropriate way forward.
