Answer: ≈ 5.2

Step-by-step explanation:

You're gonna want to use the Law of Cosines to solve:

c² = a² + b² -2abcos(R)

c² = 6² + 9² - 2(6)(9)cos(34°)

c² = 36 + 81 - 108cos(34°)

c² = 117 - 108(.82904)

c² = 27.46368

√c² = √27.46368 => 5.2405 = 5.2

Find the volume of the solid bounded by z = 2 - x2 - y2 and z = 1. Express your answer as a decimal rounded to the hundredths pl

butalik [34]

Answer:

The answer is " $(\frac{\pi}{2})$ ".

Step-by-step explanation:

$z = 2 - x^2 - y^2.........(1) \\\\z = 1.............(2)$

Let add equation 1 and 2:

Using formula: $x^2+y^2=1 \\\\$

convert to polar coordinates

$r=2$

$\theta \varepsilon (0=\pi)=z\\\\V=\int^{2\pi}_{\theta=0}\int^{1}_{\pi=0}\int^{z_{2}}_{z_1} r \ dr \d \theta\\\\$

$=\int^{2\pi}_{0}\int^{1}_{0} (Z_2-z_1)r \ dr \d \theta\\\\=\int^{2\pi}_{0}\int^{1}_{0} 1- (-1-x^2-y^2) r \ dr \d \theta\\\\=\int^{2\pi}_{0}\int^{1}_{0} (+1 \pm r^2) r \ dr \d \theta\\\\=\int^{2\pi}_{0}\int^{1}_{0} (-r^3 + r) \ dr \d \theta\\\\=\int^{2\pi}_{0} (-\frac{r^4}{4}+\frac{r^2}{1})^{1}_{0} \d \theta\\\\=\int^{2\pi}_{0} (\frac{1}{4}) \d \theta\\\\=(\frac{2 \pi}{4}) \\\\=(\frac{\pi}{2}) \\\\$

Percent 81%

Step-by-step explanation:

There are total 10×10 = 100 squares in the picture and number of shaded squares = 100 - 19 = 81

Shaded area expressed as the fraction of the whole =

Shaded area in decimals of the whole =

Shaded area in percent of the whole = = 81%
