Find the length of the diameter of a sphere with a surface area of 50.27 ft^2.
Liula [17]
Sphere Surface Area     =    <span> 4 • <span>π <span>• r²

50.27 = 4 * PI * r^2
</span></span></span>
<span>50.27 / (4 * PI) = r^2

</span> <span> <span> <span> 4.0003594946 </span> </span> </span> = r^2

r = sq root (<span> <span> <span> 4.0003594946)

radius = </span></span></span> <span> <span> <span> 2.0000898716 </span> </span> </span>

So the diameter = <span> <span> <span> 4.0001797433 </span> </span> </span>

or it is roughly 4 feet

Plz answer all measures plz ASAP thx
LiRa [457]

Lines <em>a</em> and <em>b</em> are parallel, so lines <em>p</em>, <em>q</em>, and <em>t</em> are considered to be transversals. To solve this, you make use of the fact that alternate interior angles are equal, as are alternate exterior angles, as are corresponding angles. Of course any linear pair of angles is supplementary.

∠1 = 90° — corresponding angle to the right angle above it

∠2 = 68° — the sum of 22° and angles 1 and 2 is 180°

∠3 = 112° — supplementary to angle 2 (and the sum of 22° and 90°, opposite interior angles of the triangle)

∠4 = 112° — equal to angle 3

∠5 = 68° — equal to angle 2; supplementary to angle 4

∠6 = 56° — base angle of isosceles triangle with 68° at the apex; the complement of half that apex angle

∠7 = 124° — supplementary to the other base angle, which is equal to angle 6; also the sum of angles 5 and 6

∠8 = 124° — alternate interior angle with angle 7, hence its equal.

Which of these transformations appear to be a rigid motion? <br> Please help me!!!!!
Alenkasestr [34]

The answer is the third answer choice, I and II only.


This is because both of those motions are rigid since they are just reflections and III is not a rigid motion since it is a dilation, the second triangle is bigger than the first.


Hope this helps!
