Answer:
3.5
Step-by-step explanation:
If the shape is half of a circle, you will be using this formula: A = π
Your radius is half of the diameter. r = d/2 = 3/2 = 1.5
Substitute r = 1.5 into the formula.
A = π
A = (3.14)
Use your calculator to find the answer and round your answer.
3.5
c = 4/5(kp + m)
Divide both sides by 4/5 or multiply by 5/4
5/4c = kp + m
Subtract m from both sides
5/4c - m = kp
Divide by k on both sides
(5/4c - m) / k = p
p = (5/4c - m) / k
Area of a rectangle = Lenght x width
Lenght = 80 cm
Width = 60 cm
Height = 50 cm
A = 80x 60 = 4800 cm^2
