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:
0.25 % loss.
Step-by-step explanation:
Let the cost of 1 watch be rs x then the cost of the other is rs 400 - x.
Let the sp be rs y.
So we have:
y = x + 0.05x
y = (400 - x) - 0.05(400 - x)
y = 400 - x - 20 + 0.05x
y = 380 - 0.95x
So x + 0.05x = 380 - 0.95x
2x = 380
x = 190.
and y = 190 + 0.05*190 = 199.5.
So the total selling price = 2 * 199.5 = rs 399
So final loss is [ (400-399)/ 400] * 100
= 0.25 %.

B
Step-by-step explanation:
Answer:
3^6-2 = 727
3^6-1 = 728
3^6-0 = 729
3^6+1 = 730
3^6+2 = 731
