Use A = (Pi)r^2
4.) 314.16
5.) 66.48 ( Half The Diameter Is The Radius)
Answer:
C. 128 in²
Step-by-step explanation:
We know that the opposite sides of rectangles are congruent, so 8 = 2x. If we divide 8 by 2 and 2x by 2, we get x = 4.
- This means that the other side length, (3x + 4), equals 3(4) + 4 = 12 + 4 = 16 inches
Now, the area of a rectangle is l × w, where l = length and w = width. The dimensions of this rectangle are 8 and 16, so 8 × 16 = 128 in².
Answer:
y = 5 -2/3 ( x-9)
Step-by-step explanation:
point slope form
y = y0 + m(x - x0).
m is the slope
m = (y2-y1)/(x2-x1)
( 7-5)/(6-9)
2/-3
=-2/3
The slope is -2/3
Using the point (9,5)
y = 5 -2/3 ( x-9)
A=(3.14)r^2
A=(3.14)3^2
A=(3.14)9
A=28.26ft^2
Hope it helps and is correct :)
