Answer:
1. 10 : 24 = 5 : 12 = 20 : 48 = 40 : 96
2. 2 : 3 : 5 = 4 : 6 : 10 = 8 : 12 : 20
The length of arc is 69.1 feet
<em><u>Solution:</u></em>
<em><u>The length of arc when angle given in degrees is given as:</u></em>
Where,
r is the radius
is the central angle in degrees
From given,
<em><u>Substituting the values we get,</u></em>
Thus the length of arc is 69.1 feet
Answer:
132cm ^ 2
Step-by-step explanation:
First solve the top rectangle, 4x7 = 28cm
then solve the bottom rectangle, 8x7 = 56cm
then solve the triangle, we know the entire bottom is 19cm, and 7 is subtracted, thereforth leavin 12, since there is 2 triangles its a base of 6, with a height of 8 making 48cm (and since there is 2 triangles no need to divide by 2)
28+56+48 = 132cm^2
