Answer:
9.42 m
Step-by-step explanation:
Arc AB = 2πr x (45/360)
= (2 x 3.14 x 12) / 8
= 9.42
Answer:
113.04in^2
Step-by-step explanation:
pi*6^2
36pi
substitute 3.14 for pi
36*3.14=113.04
3:2 because they all are dividable by 2
Answer:
63.2
Step-by-step explanation:
90+26.6=116.8
180-116.8=63.2
Answer:
Length: 20 or 40 feet
Width: 40 or 20 feet
Step-by-step explanation:
Area = 800 = length*width = x*(60-x)= 60x - x^2
- x^2 + 60x - 800 = 0
x = 20
Or x = 40
So length can be either 20 feet or 40 feet and width can be 40 (60-20) or 20 (60-40)
