Answer:
3017.54
Step-by-step explanation:
Volume for area of circle is A = Pie ( Or in this case 3.14 ) * radius ^ 2
Plug in the numbers 3.14 * 31 ^2
31 is half the diameter or the radius
Answer = 3017.54
For scientific notation, the number before the exponent must be between 1 and 9, inclusive.
Therefore:
A) 2.603 x 10⁻⁴
B) 538
vertical angles are equal
7x+28 = 5x+22
subtract 5x from each side
2x +28 =22
subtract28 from each side
2x =-6
x = -3
angle a
7x+28
7(-3) +28
-21+28
7
Angle A =7
