Answer:
A =78.5
Step-by-step explanation:
We need the radius to find the area of a circle
r = d/2 = 10/2 =5
The area of a circle is given by
A = pi r^2
A = 3.14 (5)^2
A =3.14 (25)
A =78.5
Answer:
z =
or z = 195.8
y=-30
a = 5
b = -7
x = 64
Step-by-step explanation:
Your answer is 6%
because 6% =0.06 x 750 =45
45x 5 (years)=225
Wrong because you need to add the -2 to the 8.... I hope this helps
