The area of every circle is (pi) (radius²) .
Radius = 1/2 of the diameter, so the area of your circle is
(pi) x (8 cm)² = 201 cm² . (rounded)
(pi) is not 3 . There's nothing wrong with approximating (pi),
but 3 is more than 4.5% wrong, and that's too much. There's
no reason why 3.14 should be too hard to handle.
Tangent 45 = height / 3
height = 3 * tan (45)
height = 3 * 1
height = 3
<span>Trapezoid area = ((sum of the bases) ÷ 2) • height
</span>
<span>Trapezoid area = (9 + 15) /2 * height
</span><span>Trapezoid area = 12 * 3
</span><span>Trapezoid area = 36

1. Input:1, output:4
2. Input:1, output:6
3. Input:5, output:8
3. Input:5, output:10
The different between the inputs and outputs are 3, 5, 3, 5. See the pattern?
Hope this helped.
Split them into triangles and rectangles.
15 x 9 = 135
(6 x 3) / 2 = 9
135 - 9 = 126
This gives you the area of the rectangle with the triangle taken out of it.
15 - 6 = 9
(9 x 6) / 2 = 27
This gives you the area of the triangle at the top.
Add these together: 27 + 126 = 153, and that's your answer!

Answer:
One is 3 to 4th power
(3 x 3) x (3 x 3)
Step-by-step explanation:
the other is
3 to 3rd power divided by nine to the fourth power...
(3 x 3) x 3 = 27
(9 x 9 ) x (9 x 9) = 2187
2187 / 27 = 81
