Answer:
176.6 inches.
Step-by-step explanation:
15 is the diameter, so 15/2 is 7.5 which is the radius
A of a circle is 3.14 x r^2
7.5^2=56.25
56.25 x 3.14=176.625
rounded makes it 176.6
 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = 4(x - 10) ← is in point- slope form
with slope m = 4
Given a line with slope m then the slope of a line perpendicular to it is
 = -
 = -  = -
 = - 
The perpendicular line passes through (- 3, 7), hence
y - 7 = -  (x - (- 3)), that is
(x - (- 3)), that is
y - 7 = -  (x + 3) → D
(x + 3) → D

1) C is because it’s exactly double the size in both width and length while the others are only gaining one or the other. For example - the a length of the squares is 5 and the length on c is 10, the base on a is 3 long, the base on c is 6. The width on a is 1 and the width on c is 2. You can put these into fractions 5/10 3/6 1/2 but they all equal 1/2. So it’s double the size of a.
