It would be 3.14(7)^2
Then 3.14*49
Multiply those two to get your area
V=B*h
To double the volume , we have to double the height
then V2=B*2h=2*V
A) as the exponent decreases by one, the number is divided by 5
B) as the exponent decreases by one, the number is divided by 4
C) as the exponent decreases by one, the number is divided by 3
D) 4⁰ = 4 ÷ 4 = 1
4⁻¹ = 1 ÷ 4 = 
4⁻² =
÷ 4 = 
E) 3⁰ = 3 ÷ 3 = 1
3⁻¹ = 1 ÷ 3 = 
3⁻² =
÷ 3 = 
After 1 year it is worth 108% of its original value
108% = 1.08
so 1.08 x 1000 = $1080
After 2nd year it is worth 92% of that $1080
92% = 0.92
so 0.92 x 1080 = $993.60
