Its quite simple. All you have to due is substitute the numbers they gave you for each letter. So.... it would look like this > 5(2) + 3(5) - 2(4) = ? Now all you have to do is solve it! Hope this helps :)
516.66 <span>km
</span>
There are 100 m in 1 km
Therefore : 880 m = 0.88 km
435 km + 80.78 km + 0.88 km = 516.66 km
The ratio of the circumference to the diameter is defined as pi
pi=circumference/diameter
that is how they got pi
in this question it woul be 15.7/5 which would be 3.14,
c=2pir
a=pir^2
c=2pir=16pi
divide both sides by 2pi
r=8
a=pir^2
a=pi8^2
a=pi64
a=64pi in²
