Answer:
V = πr²h
r = √V/πh
r = √8281 cm³/(3.14)(23 cm)
r = √8281 cm³/72.22 cm
r = √114.66 cm²
r = 10.71 cm
2x - y = 7
y = 2x - 7 this line has slope = 2
Perpendicular lines, slope is opposite and reciprocal so slope = -1/2
Answer
A . -1/2
I worked it out. The pic shows my work and answer. I got that X=1. If you have any ?’s then ask in the comments.
Hope to us helped ya!
<em>*Remember that A = angle and S = side.</em>
So remember that <u>similar figures have congruent angles and proportional sides.</u> Looking at triangles ABC and DEF, they both share 85° and 30° angles. <u>With this, the two triangles are similar by AA, or the first option.</u>
