Answer:
78.5 or 78 1/2 units
Step-by-step explanation:
The formula for the area of a circle using diameter is 1/4*pi.*d to the second power. Plug it in, and you get 78.5 or 78 1/2 units.
Equation for circumference is c = 2(pi)r
r = 1/2(d)
d = 20
So…. r = 1/2(20) = 20/2 = 10
Going back to circumference equation
c = 2(pi)(10) = 2(3.14)(10) = 62.8
Simplify brackets
(7w - 2 - w = 2(3w - 1)
simplify 7w - 2 - w to 6w - 2
(6w - 2 = 2(3w - 1)
Expand
(6w - 2 = 6w - 2)
Since both sides are equal, there are infinitely many solutions
Answer: C) INFINITELY MANY
