The area of this figure is 10
Answer:
1/5
Step-by-step explanation:
We can find the slope of a line given two points by using the following
m = ( y2-y1)/(x2-x1)
= ( 3-0)/(7 - -8)
= ( 3-0)/(7+8)
= 3/15
= 1/5
By geometry, there is a relationship between the tangent PA and the segments PB and PE, namely
PA^2=PB*PE
so
PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5
Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
r = 11
h = 4.5
π ≈ 3.14
(1/3) (3.14) (11²) (4.5) =
(1/3) (3.14) (121) (4.5) =
(1/3) (3.14) (544.5) =
(1/3) (1709.73) = 569.91
569.91 rounded to the nearest tenth is 569.9 so your answer would be 569.9 in³
