Answer:
333 in^3
Step-by-step explanation:
Circumference = pi *d
27 = pi*d
Replacing d with 2*r ( 2 times the radius)
27 = pi * 2 * r
Divide each side by 2
27/2 = pi *r
13.5 = pi *r
Divide by pi
13.5/ pi = r
We want to find the volume of a sphere
V = 4/3 pi * r^3
V = 4/3 pi (13.5/pi)^3
= 4/3 pi * (13.5)^3 / (pi^3)
4/3 pi/pi^3 * (13.5)^3
4/3 * 1/ pi^2 *2460.375
3280.5 / pi^2
Let pi be approximated by 3.14
380.5/(3.14)^2

Answer:
76 degrees
Step-by-step explanation:
this special line is an angle bisected.
that means it splits the angle at its starting point in 2 halves. as these names indicate, both parts are of equal size (half of the general angle).
we know one part (2) of this split angle : 38 degrees.
the other part (1) had to be equally sized : 38 degrees.
so, the total angle at point R is the sum of both split angles:
TRS = 38+38 = 76 degrees.
