Answer:
44 cm
Step-by-step explanation:
The circumference (C) of a circle is calculated using the formula
C = 2πr ← where r is the radius
here r = 7, hence
C = 2 ×π × 7 = 14π ≈ 44 cm ( to nearest whole number )
The two lines are parallel, therefor 90-28=internal angle=62. Using trigonometry, Cosine=a/h. Cos(62)=350/x. Rearrange to get 350/Cos(62) = 519.7(1dp)
