We can write two division problems related the given equation as follows.
Division problem one :
Here 8 is in multiplication with -2 on the left side.
so when we bring this 8 on the right side, we will have to apply opposite operation of multiplication which is division.
so dividing (-16) by 8 on the right side, we have:
Division problem two :
Here -2 is in multiplication with 8 on the left side.
so when we bring this (-2) on the right side, we will have to apply opposite operation of multiplication which is division.
so dividing (-16) by (-2) on the right side, we have:
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
