So, you know that any number with 100 as the denominator will be a fraction. All you have to do is change the 10 you have now to 100. To do that, you have to multiply BOTH numerator and denominator (top and bottom) by 10. That results in 70/100, which is equal to 70%.
The equivalent percent for 7/10 is 70%.

Area of a circle=
For radius(r)=8 km
The area of the circle is :
=
As:
Area of the circle:
The Area of the circle with the radius of 
is
Perimeter = namely the length of outside bordering,
well, this is a PENTAgon, or PENTA=5 or namely 5 sides, is regular so each side is the same length, so we have a polygon with 5 sides each measuring 40cm, well, its perimeter is just 40+40+40+40+40 = 200.
