Answer:
9 x 100 + 8 x 10 + 7 x 1000 = 7,980
Tangent Θ = opposite / adjacent
AB = short leg = opposite = 12
AC = long leg = adjacent = 5
BC = hypotenuse = 13
tangent Θ = 12/5 ⇒⇒⇒ this is in ratio form
tanΘ = 2.4 ⇒⇒⇒ this is in decimal form
Answer:
Step-by-step explanation:
radius = d/2=22/2=11
area=pi*r*r=22/7*11*11
=380.28
