Find the area of the figure
1 answer:
Answer:
<h2>A = 252</h2>Step-by-step explanation:
It's a trapezoid.
The formula of an area of a trapezoid:
b₁, b₂ - bases
h - height
<em>(look at the picture)</em>
Use the Pythagorean theorem to calculate the length <em>x</em>:
<em>subtract 144 from both sides</em>
Substitute:
[tex]A=\dfrac{30+12}{2}\cdot12=(42)(6)=252[/txt]

11. 8 * 18 = 144 in³, Option D
12. Half the height of 8 cm is 4 cm. Volume = 4 * 6 * 10 = 240 cm³, Option D
13. Double the dimensions you get 8 cm for the height, 6 cm for the radius. Then plug in. V = pi * (6)² * 8 >> pi * 36 * 8 = 288pi or ≈ 904.78, Option C
14. Half of all the dimensions are 1 in, 4 in, and 3 in. 1 * 4 * 3 = 12 in³, Option B
