11yd is the diameter and circumference is 2πr = 2π(d/2) = πd = 11π yd
Answer:
80 yd^2
Step-by-step explanation:
Since the formula for squares is s^2, we can use this to set up an equation, which is
s^2=400
If we square root this, we get
s=20
The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2
4 (i literally had to think about this cause i thought it was too easy )
Alright, lets get started.
In the question given that glacier receded 4 feet a day for a period of 25 days.
Which shows in 1 day, it recedes = 4 feet
means in 1 day, the height of the glacier gets shorter = 4 feet
So, in 25 days, the height of the glacier gets shorter = 4 * 25
So, in 25 days, the height of the glacier gets shorter
feet
It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer
Hope it will help :)
