To use the equation we need a1 and d(the common difference).
We have a1 = 57, we need to find d.
93-84 = 9; 84-75=9; 75-66=9; 66-57=9
d = 9
a350 = 57 + (350-1)(9)
a350 = 57 + (349)(9)
a350 = 57 + 3141
a350 = 3198
We must find the radius so we can plug this into the formula for surface area.
Circumference =


We are going to plug this in as our radius for the most accurate answer.
The surface area of a sphere is

Surface Area =

≈ 451.93 units

Step-by-step explanation:
You can write it by putting 55 over 100 and simplify then you get an answer of 11 over 20.
Answer:
109
Step-by-step explanation:
81-19 is 62. if you add 109 then you could do 109-19 is 90
