<u><em>Answer:</em></u>
Radius of the ball is approximately 6.5 cm to the nearest tenth
<u><em>Explanation:</em></u>
The ball has the shape of a sphere
<u>Surface area of a sphere can be calculated using the following rule:</u>
Surface area of sphere = 4πr² square units
<u>In the given problem, we have:</u>
Surface area of the ball = 531 cm²
<u>Substitute with the area in the above equation and solve for the radius as follows:</u>
which is approximately 6.5 cm to the nearest tenth

2-4 is -2
6-2 is 4
Answer:
The length of the model is 21 inches
Step-by-step explanation:
we have
The scale factor
That means
1 unit in the model represent 12 units in the actual
1 inch in the model represent 12 inches in the actual
Remember that
so
1 inch in the model represent 1 ft in the actual
The scale factor is
therefore
21 ft in the actual represent 21 inches in the model
6/7-2/3
Make sure they have the same denominators which means looking for the GCF
So the GCF is 21 in this case
6/7= 18/21
2/3= 14/21
18/21 - 14/21= 4/21
The answer is 4/21
