Answer: The area of Figure ABCDE is 79.5 square units.
Step-by-step explanation:
<em>Triangle ABC is the top triangle of Figure ABCDE.</em>
<u>Triangle ACD is the triangle on the right of Figure ABCDE.</u>
Triangle AED is the triangle on the bottom left of Figure ABCDE.
So, we need to add <em>23.85</em>, <u>29.4</u>, and 26.25 to get the area of Figure ABCDE!
23.85 + 29.4 + 26.25 = 79.5
Answer:
Step-by-step explanation:
a) r = 10/2 = 5 feet
Area of floor =πr² =3.14*5*5 = 78.5 feet²
B) h = 3 foot
Volume of cylinder = πr²h = 3.14*5*5*3 = 235.5 cubic feet
Volume of hemisphere =2/3πr³= 2*3.14*5*5*5/3=261.67 cubic feet
Volume of space inside the observatory = 497.17 cubic feet
We start out with x/3+6=-6. Subtract 6 from both sides, and you get x/3=-12. Multiply the equation by three and you get x=-36. x=-36 should be your final answer.
Lol no one is going to work that out just copy and paste into an online calculator good luck
