Answer:
15.7ft
Step-by-step explanation:
diameter= a2+b2=c2
(3)^2+(4)^2= 9+16=c^2
25=c^2(divide the square root)
c= 5
d=5 ft
find circumference:2(pie)r
2(3.14)(2.5)= 15.7ft
Use Pythagorean theorem:
Diameter² = 4² + 3²
= 16 +9
= 25
Diameter = √25 = √5*5 = 5 ft
Diameter = 5 ft
Circumference = πd
= 3.1428 * 5
= 15.714
= 15.71 ft
Radius = 5/2 = 2.5 ft
