Answer:

What is the surface area of the cylinder with height 3 mi and radius 8mil? Round your answer to the nearest thousandth

Step-by-step explanation:

SOLUTION

HEIGHT -3

RADIUS - 8

AREA - 2πr ( r+h)

$2 \times \frac{22}{7} \times 8(8 + 3) \\ \\16 \times \frac{22}{7} \times 11 \\ \\ 176 \times \frac{22}{7} \\ \\ \frac{3872}{7} \\ = 553.143$

The length of a rectangle is eight more than triple the width. If the perimeter is 168 inches, find the dimensions.

defon

Answer:

P= 2(3W + 7) + 2(W) = 110.

P= 6W + 14 + 2W = 110.

= 8W + 14 = 110.

= 8W = 110 - 14 = 96

W = 96/8 = 12- inches.

Now solve for (L) by L = 3W + 7 = 3(12) + 7 = 36 + 7 = 43- inches

7=43 inches if this help.can u mark me brainliest

Use a graphing calculator to solve the equation -2sin(theta)= 1.2 in the interval from 0 to 2pi.

elena-s [515]

Answer:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Step-by-step explanation:

As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:

$\theta=3.7\\\\and\\\\\theta=5.7$

So, it's useful to solve the equation too, in order to verify the result:

$-2sin(\theta)=1.2\\\\sin(\theta)=-\frac{3}{5}$

Taking the inverse sine of both sides:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:

$\theta\approx 3.785\\\\\theta \approx 5.64$

9) > cause 1 fl oz is .125 of a cup and multiply that by 96 which is 12 cups which is less than 13 cups
10)> cause 1 lb is 16 oz, multiply 16 by 25 which is 400, which is greater than 384 cups
11) = cause 1 yd is 36 in, so you would multiply 36 in by 8, which is 288 inches, which is the same
