Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
Umm what is this supposed to mean more information
The power of 4 means to move the decimal 4 places to the right. 6.3 x 10^4
63000
Answer: 31°
Since <DAB = 55° and <CAB = 24°, subtract 24 from 55.
55 - 24 = 31
