It is generally useful to use the formula. The procedure is to substitute the given values for the variables in the formula, then do the arithmetic.
... A = (1/2)r²·θ . . . . r is the radius, θ is the central angle in radians
Put the numbers in ...
... A = (1/2)(4 in)²·(π/3)
... A = 8π/3 in² ≈ 8.37758 in²
(50/5)/(3/5) = (50/5)*(5/3) = (50/3) = 16 2/3
Answer:
68°
Step-by-step explanation:
If its 4.5 by 4 is 56 that means it's 56 on the other side
Using the Pythagorean Theorem:
Missing side = √4^2 +8^2
Missing side = √16+64
Missing side = √80 = 8.9 (rounded to the nearest tenth)
