Find the volume of a cone whose height is 7.5cm and the base diameter is 7cm pi=22/7​

Mathematics
1 answer:
xz_007 [3.2K]3 years ago
4 0

Answer:

92.64 cm^3 (it should be smaller if using actual pi, 22/7 is larger than pi)

Step-by-step explanation:

The equation for the volume of a cone is 1/3(pi*h*r^2) So, first we need to find the radius, which is diameter over 2, so the radius is 3.5 cm. Now we know all of the variables so we can plug in to solve.

How many distinct triangles can be formed for which m∠E = 64°, g = 9, and e = 10?<br> triangle(s)
Shalnov [3]

Using the law of sines, it is found that 1 triangle can be formed with the given conditions.

<h3>What is the law of sines?</h3>

Suppose we have a triangle in which:

  • The length of the side opposite to angle A is a.
  • The length of the side opposite to angle B is b.
  • The length of the side opposite to angle C is c.

The lengths and the sine of the angles are related as follows:

\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}

Hence, for this problem, we have that the relation is:

\frac{\sin{64^\circ}}{10} = \frac{\sin{G}}{9}

\sin{G} = 0.9\sin{64^\circ}

\sin{G} = 0.8089

G = \arcsin{0.8089}

G = 54º

A triangle can have one angle of 64º and another of 54º, hence 1 triangle can be formed with the given conditions.

Find the tenth term of an arithmetic sequence if the third term is 19 and the sixth term is 37.
larisa [96]

\bf \begin{array}{|ll|ll} \cline{1-2} term&value\\ \cline{1-2} a_3&19\\ a_4&19+d\\ a_5&19+d+d\\ a_6&19+d+d+d\\ &19+3d\\ &\\ \cline{1-2} \end{array}~\hspace{5em} \begin{array}{llll} \stackrel{a_6}{37}=19+3d\implies 18=3d \\\\\\ \cfrac{18}{3}=d\implies 6=d \end{array}


since we know the <u>common difference</u> is d is 6, then to get from the 6th term to the 10th term, we use d 4 more times.

6th term..................37

7th term...................37 + 6

8th term...................37 + 6 + 6

9th term...................37 + 6 + 6 + 6

10th term...................37 + 6 + 6 + 6 + 6

.....................................61.

(02.03 MC) The temperature at a mountain base camp was −2 degrees Celsius on Thursday. Friday morning, the temperature was 1 deg
aev [14]

Answer:

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Step-by-step explanation:

To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:

(i) <em>The temperature at a moutain base camp was - 2 degress Celsius on Thursday</em>:

T_{o} = -2\,^{\circ}C

(ii) <em>Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday</em>:

\Delta T_{1} = -1\,^{\circ}C

(iii) <em>Friday evening, the temperature was 3 degrees Celsius lower that it was that morning</em>:

\Delta T_{2} = -3\,^{\circ}C

The temperature at the base camp Friday evening is:

T = T_{o}+\Delta T_{1}+\Delta T_{2}

T = -2\,^{\circ}C-1\,^{\circ}C-3\,^{\circ}C

T = -6\,^{\circ}C

The temperature at the base camp Friday evening is - 6 degrees Celsius.
