The correct answer would be Choice B: 4 square units.
When the scale factor is 1/5, that means the lengths of the sides are 1/5 of the original size. So instead of having a base of 20 and height of 10, the new triangle has a base of 4 and a height of 2.
The area of the triangle is: (4 x 2) / 2 = 4
Answer: 1 1/12
Step-by-step explanation:
1/3 + 3/4 =
1/3 x 4= 4/12
3/4 x 3 = 9/12
9/12 + 4/12 = 13/12 = 1 1/12
Answer:
V = 180 ft^3
Step-by-step explanation:
The volume of a cone is found by
V = 1/3 pi r^2 h where r is the radius and h is the height
The diameter is 12 so the radius is 1/2 the diameter or 1/2(12) = 6
The height is 5 and we are using 3 for pi
V = 1/3 (3) *6^2 *5
V = 180 ft^3
D because one thousand nine hundred twenty divided by 8 equals two hundred and forty
