Step-by-step explanation:
Since the triangles are similar
(a)
The corresponding angles are congruent , that is
∠ A = ∠ D , ∠ B = ∠ E , ∠ C = ∠ F
(b)
The ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
24 ? = 168 ( divide both sides by 24 )
? = 7

The formula for circumference is 2
r, where r is equal to radius.
It states to use 3.142 for pi
It also provides you with the diameter, not the radius, so you have to divide it by two to get 4.5
2*3.142*4.5= approximately 28.278 or 28.3
