The circumference of a circle is found by using the equation: C= 2 x PI x r
Both circles have r = 1
Circumference = 2x 3.14 x 1 = 6.28.
Diameter is 2 times the radius= 2x1= 2
The ratio of the circumference to the diameter = 6.28 / 2 = 3.14 which is the value of PI
Answer:
36 units³
Step-by-step explanation:
To find the volume of a prism, you must multiply the base times the height. 4×9=36.
Answer:
Step-by-step explanation:
1) Rewriting for the sake of clarity:
2) To solve it, we need to turn the rational exponent equal to 1 via exponent rule of product. Multiplying 2/3 by its reciprocal 3/2 we get 1, since this is an equality we need to do it on the other side.
![(x-1)^{\frac{2}{3}}=64\\\\((x-1)^{\frac{2}{3}}]^{\frac{3}{2}}=(64)^{\frac{3}{2}}\\(x-1)=\sqrt{64^{3}}\\x-1+1=512+1\\x=513](https://tex.z-dn.net/?f=%28x-1%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D64%5C%5C%5C%5C%28%28x-1%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%5D%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%3D%2864%29%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%5C%5C%28x-1%29%3D%5Csqrt%7B64%5E%7B3%7D%7D%5C%5Cx-1%2B1%3D512%2B1%5C%5Cx%3D513)
