Answer:
The diameter of the pond is 38 m.
The radius of the pond is 19 m.
The area of the pond is 361 m^2.
Step-by-step explanation:
We know that the circumference C of a circle is equal to

In this case, C is equal to 120 m.
The diameter is then:

Rounded to the nearest whole number, the diameter is D=38 metres.
The radius is equal to half the diameter, so the radius of this pond is R=19 metres.

The area can be calculated from the radius as:

The area is 361 m^2

Step-by-step explanation:
Answer:
-1/18
Step-by-step explanation:
First, you have to change both fractions to have like denominators. The LCM of 2 and 9 is 18.
Second, you have to multiply -1/2 by 9/9 to get a denominator of 18. -1/2 x 9/9 is - 9/18.
Third, you have to multiply 4/9 by 2/2 to get a denominator of 18. 4/9 x 2/2 = 8/18.
Fourth, -9/18 + 8/18 = -1/18
Hope this helps!
