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
Answer:
d=-18
Step-by-step explanation:
8 x 5 x 5 = 200cm^3
8 x 8 x 1 = 64 cm^3
200 + 64 = 264cm^3
Answer: Surface area= 54
Step-by-step explanation:
To find the surface area of a cube you do 6 times s^2
S is the side length. In this case that is 3 cm. S^2 is 9
So now you do 6 times 9, and that is 54.
So, the surface area is 54.
