(Pi* r^2) = the area of the circle, or cross section
= 201.06
Multiply by the height for volume, *12
= 2412.74 -- this is the total volume
now *2/3 to get the answer
=1608.5
I dont know what the units are, they aren't given
Answer:
Use your CASIO calculator and put inverse SIN of 8/15
Best regards
Hi!
The point where the three altitudes of a triangle intersect is called the orthocenter.
Altitudes are lines which pass through the the vertex of a triangle, and bisect the other side.
There are three other points like an orthocenter; an incenter, a circumcenter, and a centroid. They're where the angle bisectors, the perpendicular bisectors, and the medians of a circle intersect, respectively.
Hope this helped!
Answer:
S=157
Step-by-step explanation:
an= a1+(n-1)d
a2=80+(2-1)(-3)
a2=80-3
a2=77
Sn=(a1+an)*n/2
S2=(80+a2)*2/2
S2=(80+77)*1
S2=157
Answer:
x = 41
Step-by-step explanation:
By the Angle Bisector Theorem, which basically states that EG / GD = EH / DH, we get this: 49 / 35 = 58.8 / (x + 1). Now, if we simplify, we get 7/5 = 58.8 / (x + 1). Cross-multiply to get 294 = 7x + 7, or 7x = 287. From here, it is obvious that x = 41.
