Area of circle= pi times radius^2

diameter=2 times radius
radius=diameter/2
diameter=12
radius=12/2
radius=6

pi times r&+^2
pi times 6^2
pi times 36
aprox pi=3.14

Factor completely 12a^3d^2 – 6ad^3
lorasvet [3.4K]

Answer:

12a^3d^2-6ad^3

To factor an integer, we need to divide it by the ascending sequence of primes 2, 3, 5

In the end, the number of times each prime divides the original integer becomes its exponent.

Prime number 2  to the power of 2 equals 4 .

Prime number 3 to the power of 1 equals 3 .

2^{2} \times 3\times a^{3} \times b^{2} -(2\times3)ad^{3}

Result:-  6ad^2\left(2a^2-d\right)

Find the volume of a right circular cone that has a height of 18.6 m and a base with a radius of 15.5 m. Round your answer to th
ExtremeBDS [4]

This one should have come before the other one. We apply the cone formula

V = \frac 1 3 \pi r^2 h

V = \frac 1 3 \pi(15.5)^2 (18.6) \approx 4679.6 \textrm{ cubic meters}

Simplify and write the trig expression in terms of sin and cos
dsp73

We have:

cot(-x)cos(-x)+sin(-x)=-\frac{1}{f(x)}

Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:

-sin(x)-cot(x)cos(x)=-\frac{1}{f(x)}

We clear f(x):

f(x)=\frac{1}{sin(x)+cot(x)cos(x)}=\frac{1}{sin(x)+\frac{cos(x)}{sin(x)}cos(x)}=\frac{1}{sin(x)+\frac{cos^2(x)}{sin(x)}}

we simply what we can:

f(x)=\frac{1}{\frac{sin^2(x)+cos^2(x)}{sin(x)}}=sin(x)

Thus, the correct answer is;

f(x)=sin(x)

Add and subtract rational numbers without common denominators. Show work! 1. 7/4 - 3/2 - 2/5 = 2. - 5/16 + 3/4 + 1/8 = 3. 3/4 -
alukav5142 [94]
\dfrac{7}{4}  -  \dfrac{3}{2} -  \dfrac{2}{5}

= \dfrac{7 \times 5}{4 \times 5}  -  \dfrac{3 \times 10}{2 \times 10} -  \dfrac{2 \times 4}{5 \times 4}

= \dfrac{35}{20}  -  \dfrac{30}{20} -  \dfrac{8}{20}

= \dfrac{35-30-8}{20}

= \dfrac{3}{20}

---------------------------------------------------------------

-\dfrac{5}{16}  + \dfrac{3}{4} + \dfrac{1}{8}

= -\dfrac{5}{16}  + \dfrac{3 \times 4}{4 \times 4} + \dfrac{1 \times 2}{8 \times 2}

= -\dfrac{5}{16}  + \dfrac{12}{16} + \dfrac{2}{16}

= \dfrac{-5+ 12 + 2}{16}

= \dfrac{9}{16}

---------------------------------------------------------------

\dfrac{3}{4} -  \dfrac{1}{3} - \dfrac{7}{12}

= \dfrac{3 \times 3}{4 \times 3} -  \dfrac{1 \times 4}{3 \times 4} - \dfrac{7}{12}

= \dfrac{9}{12} -  \dfrac{4}{12} - \dfrac{7}{12}

= \dfrac{9 - 4 - 7}{12}

= -\dfrac{2}{12}

= -\dfrac{1}{6}

---------------------------------------------------------------

\dfrac{2}{9}  -  \dfrac{2}{12} -  \dfrac{2}{3}

= \dfrac{2}{9}  -  \dfrac{1}{6} -  \dfrac{2}{3}

= \dfrac{2 \times 2}{9 \times 2}  -  \dfrac{1 \times 3}{6 \times 3} -  \dfrac{2 \times 6}{3 \times 6}

= \dfrac{4}{18}  -  \dfrac{3}{18} -  \dfrac{12}{18}

= \dfrac{4 - 3 - 12}{18}

= - \dfrac{11}{18}
