Answer:
C
Step-by-step explanation:
Since the exponent on the 10 is negative, we need to move the decimal point to the left instead of the right. After moving the decimal point on the 2.5 to the left 4 places, we see that the answer is 0.00025.
1/8.
16^-3/4
= (⁴√16)^-3
= 2^(-3)
= 1 / 2^3
= 1/8.
314.2
A = π r2
10x10 = 100
100 x 3.1416 (Only a little bit of pi)
314.15927
