Answer:
<h2>12 in²</h2>Step-by-step explanation:
<h3>to understand the solving steps</h3><h3>you need to know about:</h3>diameter:4in
π≈3
<h3>to solve:</h3>redious
area of the circle
<h3>let's solve:</h3>to figure out the area
we need to figure out the redious first
so the redious is 4/2 =2in
and the area of the circle is
πr²
3×2² in²
3×4 in²
12 in²

Answer:
perpendicular:
parallel:
Step-by-step explanation:
original line:
y = -5x + 5
=> 5x + y = 5
m = -5/1 = -5
perpendicular:
m = 1/5
L: x - 5y = k
(7, -5) -> L
7 - 5 * (-5) = k
=> 7 + 25 = 32 = k
L: x - 5y = 32
parallel:
m = -5
L: 5x + y = k
(7, -5) -> L
35 - 5 = 30 = k
L: 5x + y = 30
