Add 6+7+9, which gives 22.
Divide 44 by 22, which is 2.
Multiply the ratio by 2:
(6 : 7 : 9) * 2 = 12 : 14 : 18
The lengths of the sides are 12cm, 14cm, 18cm.
I got 1.4 for this one..............
Answer:
I suggest you convert them to improper fractions. Find a common denominator and change back to mixed number.
Step-by-step explanation:
Answer:
D). 659.73 in^3.
Step-by-step explanation:
The volume of a cone = 1/3 π r^2 h
The volume of the large cone = 1/3 π 6^2 * 20 in^3.
The plane passes through the midpoint of the cone so the height of the small cone = 10 in
and the radius of this cone is 1/2 * 6 = 3 in.
The volume of the small cone = 1/3 π 3^2 * 10 in^3.
So the volume of the blue section
= 1/3 π 6^2 * 20 - 1/3 π 3^2 * 10
= 659.73 in^3.
