This problem involves using the Pythagorean Theorem which is a^2+b^2=c^2
We already have the values of a and c, but b is unknown. So we plug in: 11^2+b^2=20^2
121+b^2=400
b^2=279
b=sqrt(279)
b=16.7
So the answer is about 16.7 ft
Hope this helped!
Answer:
19.63 m^2
Step-by-step explanation:
This is an Area=pi r^2 equation so it would be 3.14*2.5^2
Its too small I cant read it
