A cone that is sliced through the vertex would make the shape of a triangle.
You are told the h eight is 10 cm and the radius is 4 cm.
The radius would be half the base, so the base would be 4 * 2 =8 cm.
The area of the triangle is found by multiplying the base by the height, then dividing by two.
Area = 8 x 10 = 80
80 / 2 = 40 square centimeters.
Answer:
80km
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (1.2, 1.0, 96) as shown below:

Next we cross multiply. We multiply 1.2 and x, and we multiply 96 and 1.0.
1.2(x) = 1.2x
96 x 1.0 = 96
Now, lets put the values above back into the equation:
1.2x = 96
Lets solve this equation. First we divide 96 by 1.2.
1. 
2. 
This means that our answer is 80km.
The answer is d.61. 66+7=73. 13+8=21. 52+9=61. 10+10=20
Answer:
B. 30x
D. x(45-15)
Step-by-step explanation:
The distributive property lets you factor out the common factor of x. The sum of coefficients can be simplified to a single coefficient.
45x -15x = x(45 -15) = 30x
X2+5x=0
7x+0
divide both sides by 7
7 divided by 0 is 0
x=0
0=0
