C, since the radius is 10 multiply by 2 and 100 x 3.14 is 314

The approximate area of the given circular pond is 314 square meter.

Step-by-step explanation:

Since, the diameter of the circular pond = 20 meter,

⇒ Radius of the pond = 20/2 = 10 meter.

Thus, the area of the pond,

$A=\pi\times (10)^2$

$=\frac{22}{7} \times 100$

$=\frac{2200}{7}=314.285714286\approx 314\text{ square meter}$

Hence, The approximate area of the given circular pond is 314 square meter.

The number is 160

Step-by-step explanation:

Let the No be x

Then:

4/5x - 3/4x=8

Take out x since is common

X(4/5-3/4)=8

X=160
