1. 15*15= 225
2. 8*8= 64
3. 225+64= 289
4 . 17*17=289
Answer:
300
Step-by-step explanation:
V=4/3 * pi* r^3
If you sub in 100 for V, do some manipulation you get r cubed to equal 23.78.
Now put the value of 23.78 in for r cubed and V comes out to be 300
D because 6/20 is correct and the three wrong super wrong hope it helps
297 cm is the total surface area of the square pyramid
Not easy to graph but
multily first equaiton by -2 remember to flip sign
-2x+4y>-6
add to other equaiton
2x-2x+y+4y>-6+8
5y>2
divide by 5
y>2/5
subtitute
2x+2/5>8
subtract 2/5 from both sdies
2x>7 3/5
divid eby 2
x>38/10=19/5=3 4/5
x>3 4/5
y>2/5
just shade the area in that zone, not including point (0,0)
