Answer:

25.12

Step-by-step explanation:

1. Use the formula for the area of a circle to find the radius

A=\pi r^2

50.24=\pi r^2

16=r^2

\sqrt{16} =r

4=r

2. Use this value to find the circumference

C=2\pi r

C=2\pi 4

C=2(12.56)

C=25.12

What tests are used to determine the radius of convergence of a power series? A. Divergence TestB. Root Test C. Comparison Test
REY [17]

Answer:

The radius of convergence is half of the length of the interval of convergence. If the radius of convergence is R then the interval of convergence will include the open interval: (a − R, a + R). To find the radius of convergence, R, you use the Ratio Test.

Wilbur runs 3.2 km every morning how many feet are in 3.2 km given that 1 mile = 1.609 km and 1 mile = 5,280
Nonamiya [84]
1.609/5280 = 3.2/x....1.609 km to 5380 ft = 3.2 km to x ft
cross multiply because this is a proportion
(1.609)(x) = (5280)(3.2)
1.609x = 16896
x = 16896/1.609
x = 10,500 ft <===
