Answer:
the population would be 30.28 billion by 2020
Step-by-step explanation:
y=6.08 + 1.21x
y = 6.08 + 1.21(20)
y = 6.08 + 24.2
y = 30.28
As the exponent is negative, we can rewrite the expression as (125/64) raised to the power 2/3.
So, (125/64) raised to the power 2/3 can also be written as [(5/4) raised to the power 3] raised to the power 2/3. The exponents will multiply and the final exponent will be 2.
Hence the answer will be (5/4) squared.
Therefore the answer is (24/16).
A = pi * r^2
radius 14 ft
A = 3.14 * 14^2
A = 3.14 * 196
A = 615.44...rounds to 615
radius 10 ft
A = 3.14 * 10^2
A = 3.14 * 100
A = 314
difference is : 615 - 314 = 301...I guess it is C...because of the rounding
