a) 4.71ft
b) 3.53ft^2
Step-by-step explanation:
Perimeter is 1/2 the circumference
1/2 Circumference = 2*pi*radius
Radius = 1/2 Diameter
Radius = 3/2 = 1.5ft
Circumference = 2*pi*1.5ft = 9.42
1/2 Circumference = 4.71
4.71ft is the perimeter.
The area is 1/2 that of a full circle
A = pi*r^2
A = 3.14*1.5*1.5
A = 7.065ft^2
1/2 A = 3.53ft^2
Answer:
slope = -4/5
y intercept = -4
Step-by-step explanation:
-5y = 4x+20
divide each side by -5
y = 4x/-5 + 20/-5
y = -4/5 x -4
it is in the form y = mx +b where m is the slope and b is the y intercept
m = -4/5 and b = -4
Answer: 15
