Area of a circle is

. The first one, a, the radius squared is 8*8=64. So

. If you multiply in pi as 3.14, you'll have 200.96 square inches. The second one, b, the radius squared is 10*10=100. So

square kilometers. If you multiply in pi as 3.14 you'll have 314 square kilometers. The third one, c, the radius squared is 14*14=196. So

. Or you could multiply in pi as 3.14 to get 615.44 yd squared. For the last one, d, the radius squared is 22*22=484 cm. Therefore,

, or multiply in 3.14 for pi to get 1519.76 cm squared. There you go!
Answer:
The fourth term is -102----------------------------------------------
Explanation:
The term after the nth term is generated by this rule

which means that we first
Step 1) multiply the nth term (

) by -4
Step 2) Add the result of step 1 to the value 2 to get the next term in the sequence
Let's follow those steps above to generate the first four terms
The first term is

. In short, the first term is 2
The second term is...





So the second term is -6
The third term is...





The third term is 26
Finally, the fourth term is...




The fourth term is -102.
