Answer:
26.22in²
Step-by-step explanation:
First get the radius using the formula of a circumference.
C = 2πr = 18.2
2(3.14)r = 18.2
6.28r = 18.2
Divide both sides by 6.28 to get r
r = 2.89
Now get the area of a circle using the formula:
A = πr²
A = 3.14(2.89)²
A = 3.14(8.35)
A = 26.22in²
Hey There! I can help you by explaining how to solve it but not answering sorry! Anyhow, To find the volume of a square based pyramid I suggest you start with the square and do L x W. Than Solve the triangles by using formula 0.5 * b * h. Hint: On the bottom triangle use 8cm from the square with the 3.8cm. Hope you now understand and can find the answer!
This is an incomplete question, the image is shown below.
Answer : The correct option is, (a) 19°
Step-by-step explanation:
Opposite angles : These are the angles in which a pair of parallel lines are cut by tranversal then the two angles share the same corner.
Opposite angles are also congruent angles, that means they are equal.
As we know that the opposite angles are equal.
And, (3x - 8)° & (2x + 1)° are alternate interior angles.
Thus, the expression will be:
(3x - 8) = (2x + 1)
3x - 8 = 2x + 1
3x - 2x = 8 + 1
x = 9
(3x - 8)° & (2x + 1)°
(3(9) - 8)° & (2(9) + 1)°
19° & 19°
Therefore, the measures of the marked angles is, 19°
