Answer:
AC= 20
Step-by-step explanation:
since the two figures are similar, CB Is congruent to FD
since image/preimage, 12/3 =4
The dilation is 4.
AC is congruent to EF
EF=5
4 x 5 = 20
AC=20
someone correct me if im wrong :)
Answer:
Perimeter = 317 m
Step-by-step explanation:
Given track is a composite figure having two semicircles and one rectangle.
Perimeter of the given track = Circumference of two semicircles + 2(length of the rectangle)
Circumference of one semicircle = πr [where 'r' = radius of the semicircle]
= 25π
= 25 × 3.14
= 78.5 m
Length of the rectangle = 80 m
Perimeter of the track = 2(78.5) + 2(80)
= 157 + 160
= 317 m
Therefore, perimeter of the track = 317 m
If its volume (Not so sure about surface area?) than its 432 inches^3
