$\textrm {Cylinder volume :}$

$\mathrm {Volume = \pi r^{2}{h}}$

$\mathrm {Volume = 3.14 \times (\frac{4}{2})^{2} \times 3}$

$\mathrm {Volume = 3.14 \times 12}$

$\mathrm {Volume = 37.68cm^{3}}$

$\textrm {Rectangular prism volume :}$

$\mathrm {Volume = length \times width \times height}$

$\mathrm {Volume = 6 \times 5 \times 7}$

$\mathrm {Volume = 30 \times 7}$

$\mathrm {Volume = 210cm^{3}}$

$\textrm {Total volume of composite figure :}$

$\textrm {Volume of cylinder + volume of rectangular prism}$

$\mathrm {37.68 + 210}$

$\mathrm {247.68cm^{3}}$

Given the following perfect square trinomial, fill in the missing term. <br><br> x2 − 16x + ____

soldier1979 [14.2K]

To make that a perfect square polynomial,
follow these steps:
1. Take the co-efficient of x term: here -16
2. Divide it by 2: -16/2 = -8
3. Square it. : (-8)^2 = 64

Thats it! 64 is the missing term you need :)

A kite is currently flying at an altitude of 19 meters above the ground. If the angle of elevation from the ground to the kite i

polet [3.4K]

Visualize the kite as a triangle, with the point where the kite is anchored being 'A', the kite being 'B', and the point directly below the kite being 'C'. We know that line segment BC is 19 meters, and can use trigonometry to find the length of the string, line segment AB. The operator 'sin' can be calculated by dividing the opposite leg over the hypotenuse, so given the angle 'A', we can solve for the hypotenuse. $sin(33)= \frac{19}{x}$ . If we solve for 'x', we get $x= \frac{19}{sin(33)}$ . Plug 19 over sin(33) into your calculator and you get 34.885, so the answer is A, 35 feet
