Answer:
8.3
Step-by-step explanation:
<u>do whats in the brackets first.</u>
13-17-1.3= -5.3
<u>rewrite the equation</u>
3-7+2-[-5.3]+5
3-7+2= -2
<u>rewrite the equation</u>
-2-[-5.3]+5
when 2 negative signs are together u change it to a positive sign.
<u>rewrite the equation</u>
-2+5.3+5
-2+5.3= 3.3
<u>rewrite the equation</u>
3.3+5=8.3

Answer: 4in
Step-by-step explanation:
Volume of a cylinder = πR²H
Volume of a cone = 1/3πr²h
πR²H = 1/3πr²h
π is very common so it could be cancelled, so the equation now becomes
R²H = 1/3r²h
3R²H = r²h
Now substitute for the values
h = 3 x 2² x 3
--------------
3²
= 9 x 4/9
= 4in.
Therefore, the height of the cone
h = 4in.
