Answer:

4/25 would be the answer as;

-1/2 + 1/3 = -0.16666666666

Step-by-step explanation:

‑1/2+(3/4•4/9) =

-1/2 + (1/3) = -4/25

-0.16

However true answer is  16666666666/100000000000. = 0.1666666666

The rule is when fractions reoccur, we show closest and -4/25 is closer than -1/6

-1/6

Reduce the numbers with the GCF which in this case is 4

3/4•4/9=1/3

-1/2+1/3= -1/6

The circumference of a circle is 19 pi meters. What is the radius in meters?
Sliva [168]

Answer:

<h3>Area of a circle in terms of radius:</h3>

Area = π·r^2 = 3.14·9.5^2 = 283.5 square meters(*)

Area of a circle in terms of diameter:

Area = π·(d/2)^2 = 3.14·(19/2)^2 = 3.14·(9.5)^2 = 283.5 square meters(*)

Area of a circle in terms of circumference:

Area = C^2/4π = 59.69^2/4π = 3562.9/(4·3.14) = 3562.9/12.56 = 283.5 square meters(*)

(*) 283.52873698648 meters, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Step-by-step explanation:
