The surface area of a sphere is

where r is the radius;
The circumference is

so that

using this value we can evaluate the surface area of 1 ball as:

For 100 ball you get:
If you mean -10.0 - (-2.3) then the answer is -7.7
The GCF of the first two is 4p³q².
The GCF of the second two is 8pq⁵.
The GCF of the third two is 4p²q⁵.
The GCF of the fourth two is 8p²q.
The GCF of the fifth two is 4p²q.
To find the GCF of each pair, find the greatest number that will divide into each coefficient. As for the variable portions, choose the variable that has the smallest exponent from each pair.
Answer:
4700 minus 1200 = 3500
Step-by-step explanation:
