Answer:
Curved surface area of a cone =πrl.
3.142×8×15=377.04cm
Given:
Point D is the centroid of Triangle ABC and DE = 9.
To find:
The measures of CD and CE.
Solution:
We know that, centroid is the intersection of medians and it divides each median in 2:1.
In triangle ABC, CE is a meaning and centroid D divided CE in 2:1. So,
Let the measures of CD and DE are 2x and x respectively.
DE = 9 (Given)
Now,
And,
Therefore, the measure of CD is 18 units and the measure of CE is 27 units.
Answer: (-2,4)
Step-by-step explanation:
When you go up any number of units, you add it to the y-coordinate. So -3 + 7 = 4. That would make it, (2,4). The next step would be reflecting it across the y-axis. And whenever you reflect across the y-axis, the x-coordinate always changes.
I beleive it is 14 and 1 quarter in.
Answer:
This is a theory.
Step-by-step explanation:
The sialic continents, mafic ocean floors, the crust, the mantle and the core were all formed while the early melted Earth cooled and differentiated as low density minerals floated to the surface and heavy, denser minerals sank to the center.
This is a theory.
