Area of an entire circle = pi * r^2

Area of a sector = angle / 360 * pi * r^2

Givens

angle = 140

radius = 8

Solution

Area = (140/360) * 3.14 * 8^2

Area =0.3889 * 3.14 * 64

Area = 78.15

4 2/3 divide by 1 2/3

sladkih [1.3K]

Answer:

14/5

Step-by-step explanation:

I'd suggest rewriting both mixed numbers as improper fractions. Then we'd have:

14/3 and 5/3

Dividing 14/3 by 5/3 is equivalent to dividing 14 by 5, since the denominators are the same (3).

Quotient is 14/5.

Identify whether the series summation of 8 open parentheses 5 over 6 close parentheses to the i minus 1 power from 1 to infinity

Leto [7]

$\displaystyle\sum_{i=1}^\infty\8\left(\dfrac56\right)^{i-1}$

This is a geometric series with a common ratio between successive terms that is less than 1 in absolute value. This means the series will converge. The value of the sum is $\dfrac8{1-\frac56}=48$ .
