The wrong statement: The volume or the smaller cone cannot be determined because its height is unknown.
We already know that the larger cone has a height of 8 cm and that the smaller cone is just 1/4 of 8 cm.
8×1/4 = 2 cm.
You can still find its volume by using the formula 1/3πr^2.
Answer: A
Step-by-step explanation: I just makes since to me. Suck that the teacher wont give you the answer.
Answer:
(3,2)
Step-by-step explanation:
Let's solve this via elimination method:
By subtracting equation 2 from equation one we obtain:
Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:
Therefore the solution for the system of equations is:
x=3 and y = 2 as an ordered pair we have (3,2)
Answer:
Option C is correct.
Equation of a line passing through (0,6) and (9,0).
Explanation:
Given the two points (0, 6) and (9 ,0).
To find the equation for the given two points and is,
; where m is the slope and is given by:
First find the slope m:
Substitute this value in equation of line:
or
⇒
Therefore, the equation for the given point is:
