Formula is π * r^2
π = about 3.14 and the radius is half of the diameter so 28/2 = 14
3.14 * 14^2 = 615.44
B
The ratio of height : shadow =44/1313
Therefore height of the tree,x=3434*(44/1313)
=115.08 ft
If you meant 13 and 34 as the length of shadows respectively, then also x=115.08 ft
78×45/100
=35.1. As a result, 35.1 is 45% of 78. Hope it help!
