Answer:
23 inches
Step-by-step explanation:
Circumference = 2πr
72 = 2×3.142×r
Divide through by 2 × 3.142
r = 
r = 11.458 inches
Diameter = 2r
Diameter = 2* 11.458 = 22.92
= 23 inches to the nearest inch
For a dilation centered around the origin
Dk (x,y) = (kx, ky)
So let's say you have a rectangle PQRS where
P = (0,0)
Q = (4,0)
R = (4,4)
S = (0,4)
To get the dilation of this PQRS to P'Q'R'S' with scale factor 1/4 you multiply every coordinate by 1/4.
P' = (0.0)
Q' = (1,0)
R' = (1,1)
S' = (0,1)
The new cordinates for point q(1,0)
It is x=1 because it just is
Answer:
125.6 cm²
Step-by-step explanation:
the area of sector = 225/360×3.14×8²
= ⅝ × 3.14 × 64
= 3.14 × 40
= 125.6 cm²
Answer is B
Explanation:
Divide -3/4 which equals -0.75
Then divide 5/8 which equals 0.625
Now look at the answers and divide the ones that are in fractions to get a decimal
The answer is B because -1/2 = -0.5 and that is greater than -0.75 and less than 0.625
Sounds confusing sorry
