Answer:
r = 5 cm
Step-by-step explanation:
A = πr²
78.53 = (3.14)r²
divide by 3.14
25 = r²
r = ±5
r = 5

Answer:
Point slope form
Step-by-step explanation:
Given

Required
Determine the form of linear equation
A linear has just three forms:
1. The slope intercept form.: This is always in form of 
2. The point slope form: This is always in form of 
2. The standard form: This is always in form of 
<em>By comparison, the three forms with the question, we can see that option B answers the question.</em>
The statement " <span>y </span><span>varies directly as </span><span>x </span><span>," means that then </span><span>x </span>increases,<span>y </span><span>increases </span><span>by the same factor so we have: y/x=k
for question 1 then: 15/5=3
so the direct variation equation is y=3x
Now if x=9 you only have to replace x in your equation and you get:
y=3*9=27</span>
