It’s 0.775x +2.5 =correct
Its the 4th one have a great day
Your answer is 100ft. This is because to find the radius when you already know the diameter you have to divide the diameter by 2.
Radius of circle= 4
a) circle circumference=2(pi)r
circumference=2(pi)4=25.13
P=2W+2L
p=2(5)+2(10)
P=30
b) area of circle=pi(r^2)=pi(16)=50.27
area of rectangle=L×W= 5×10= 50
c) I think you can figure it put
