Answer:
B and D
Step-by-step explanation:
the opposite of -6 is positive 6
V=4/3 pi r^3.
4/3r^3=1372/3,......r^3=343, r=7 inches
As they are similar corresponding sides are in the same ratio, so
18/15 = x / 4
x = 4*18 / 15
x = 4.8 answer
y = 0x +0
this line is straight up and down so it has a slope of 0 and it never crosses the y axis so it has a y intercept of 0.
That would be 1953.08
diameter = <span>circumference/pi, so reverse it and multiply 622 by 3.14</span>
