Geometry <br> Surface area and volume
Zigmanuir [339]

Answer:

volume=558.9

Step-by-step explanation:

find the volume of the cone and the hemisphere and add them together

<u>cone:</u>

Vcone=\pi r^{2} \frac{h}{3} \\\\V=\pi (5.3)^2(\frac{8.4}{3} )\\V=\pi (28.09)(2.8)\\V=247.09\pi \\V=247.1

<u>hemisphere:</u>

<u></u>Vhemisphere=\frac{2\pi r^3}{3} \\V=\frac{2\pi (5.3)^3}{3} \\V=\frac{2\pi (148.877)}{3} \\V=\frac{297.754\pi }{3} \\V=\frac{935.421}{3}\\ V=311.8

<u>add the volumes together:</u>

<u></u>Vol=247.1+311.8\\Vol=558.9

A line includes the points (0, 3) and (-1, -1). What is its equation in slope-intercept form?
SpyIntel [72]
Answer: 
y = 4x+3

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

Explanation:

use the slope formula first
m = (y2-y1)/(x2-x1)
m = (-1-3)/(-1-0)
m = (-4)/(-1)
m = 4
The slope is m = 4

The y intercept is b = 3 because this comes from the point (0,3)
The x value is always 0 for the y intercept. This is where the graph crosses the y axis

Since m = 4 and b = 3, we go from y = mx+b to y = 4x+3

You leave home and walk 3 blocks east, then 4 blocks north. How far are you from<br><br>home?
lara31 [8.8K]
I believe the answer would 5 blocks

If you go 3 blocks East and 4 north, they are like the straight sides of a triangle, so to find the diagonal distance, or the shortest distance, you would find the diagonal side of a triangle it is
A squared + B squared = C squared

So 3x3 = 9
And 4x4 = 16
16+9=25
And the square root of 25 is 5

Please correct me if I am wrong and have a good day
