Answer:
5544 cm²
Step-by-step explanation:
Radius of circle = r
Circumference = 2πr
2πr = 264
22/7*r = 132
r = 132*7/22
= 42 cm
Area = πr²
= 22/7*42*42
= 5544 cm²
Answer:
![27^{\frac{1}{5}} = \sqrt[5]{27}](https://tex.z-dn.net/?f=%2027%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D%20%3D%20%5Csqrt%5B5%5D%7B27%7D%20)
Step-by-step explanation:
Rule of exponents:
![a^{\frac{1}{n}} = \sqrt[n]{a}](https://tex.z-dn.net/?f=%20a%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%7D%20)
Apply the rule to this case:
![27^{\frac{1}{5}} = \sqrt[5]{27}](https://tex.z-dn.net/?f=%2027%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D%20%3D%20%5Csqrt%5B5%5D%7B27%7D%20)
No, I simply apply t=2 to the equation 16t2, and get 64 which is less than 75ft, so it would take longer time to hit the ground. So the answer is no I think.
Cos (π/2 - x) = sin x = 3/5
tan x = sin x / cos x = 3/5 / 4/5 = 3/4
csc x = 1/sin x = 1 / 3/5 = 5/3
sec x = 1/cos x = 1 / 4/5 = 5/4
cot x = 1/tan x = 1 / 3/4 = 4/3.
