What is the base area of the cone?

Mathematics

Angelina_Jolie [31]3 years ago
4 0

Answer:

Step-by-step explanation:

In order to find the area of the circle base, we need the radius, and we don't have it. We'll use the volume to find the radius, as follows:

V=\frac{1}{3}\pi r^2h and fill in the givens:

75=\frac{1}{3}\pi r^2(5) and solve that for r;

r=\sqrt{\frac{3(75)}{5\pi} } so

r = 3.784698783 and plug that in for the radius to find the area of the circle base:

A=\pi r^2 so

A=\pi (3.784698783)^2 gives you that

A = 45 meters squared, exactly. No decimal.

Provide me three coordinate points for the following, given the Slope and Y-intercept. 5. Slope = 7/9, Y intercept = 12(give me
madam [21]

Since we have that the slope is m = 7/9 and the y-intercept is b = 12, we can write the equation of the line in slope-intercept form:

\begin{gathered} y=mx+b \\ \Rightarrow y=\frac{7}{9}x+12 \end{gathered}

to find three coordinate points, we can use arbitrary values on x to get the y-coordinate. To make things easier, let's use x = 9, 18 and 27:

\begin{gathered} x=9 \\ \Rightarrow y=\frac{7}{9}(9)+12=7+12=19 \\ x=18 \\ \Rightarrow y=\frac{7}{9}(18)+12=7(2)+12=14+12=26 \\ x=27 \\ \Rightarrow y=\frac{7}{9}(27)+12=7(3)+12=21+12=33 \end{gathered}

therefore, the line with slope m = 7/9 and y-intercept 12 passes through the three points (9,19), (18,26) and (27,33)
