Answer: B. h = 7.5 cm ; r = 10 cm
Given:
Cylinder
Cone
Volume of Cylinder = π r² h
= 3.14 * (5cm)² * 15cm
= 3.14 * 25cm² * 15cm
= 1,177.50 cm³
Volume of the cone = 1,177.50 cm³ * 2/3
= 2355 cm³ ÷ 3
= 785 cm³
Volume of the cone = π r² h/3
a) 3.14 * 15² * 5/3 = 1177.50 cm³
b) 3.14 * 10² * 7.5/3 = 785 cm³
c) 3.14 * 7.5² * 10/3 = 588.75 cm³
d) 3.14 * 5² * 15/3 = 392.50 cm³
Answer:
-3
Step-by-step explanation:
The equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 4x-3
4 is the slope and -3 is the y intercept
Answer:
4/10
Step-by-step explanation:
the total is 10 and there are 4 red marbles.
To find the pre image you need to back track on the image. To get to the image you used (x-6,y+8). Now you need to use the exact opposite to get back to the pre image. For this you would change the signs to look like (x+6,y-8). Now we just apply this to (-4,1).
(-4+6,1-8)
(2,-7) should be the pre image point.
Answer:
y = 1/2x -4
Step-by-step explanation:
Subtract 1 from both sides of the equation and simplify.
y = 1/2(x -6) -1
y = 1/2x -3 -1
y = 1/2x -4
