Since r = h, we can substitute that into the equation
<span>V = pi * r^2 * r = pi * r^3 </span>
<span>Since we know the volume, we can put that in too. </span>
<span>64 pi = pi * r^3 now let's divide both sides by pi. </span>
<span>64 pi/pi = pi * r^3/pi </span>
<span>64 = r^3 </span>
<span>cuberoot(64) = r </span>
<span>cuberoot (2^6 )=r </span>
<span>4 = r</span>
Answer:
166
Step-by-step explanation:
5/2=2.5
415/2.5
=166
Step-by-step explanation:
I'll leave the drawing part to you. However, you just have to note that if each of the tile is 1/2 ft, the height should be 5 squares and the width is 9 squares. The area of the section of the wall is calculated by multiplying the height and the width.
A = H x W = (2 1/2 ft) x (4 1/2 ft) = 11.25 ft²
Answer:
4140
Step-by-step explanation:
The formula for sum of interior angle is (n-2)180
so since the number of side is 25. substitute 25 in place of n
which is (25-2)180. which is 4140
