Answer:
Step-by-step explanation:
To find the surface area of a cone, one uses the following formula,
Where (r) is the radius of the base of the cone, and (h) is the height of the cone, () represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
Substitute,
Simplify,
Inverse operations,
Now one can use the formula to find the surface area of a cone, substitute in the given values, and solve,
Substitute,
Answer:
7
Step-by-step explanation:
448 divided by 32 is 14 so then do 14 times 1/2 to get 7 centimeters
From the word itself, an angle bisector is a line segment that divides the angle into two equal parts. Take this problem for example. The angle is FGI, which means that the vertex is at point G. Hence, you create a line segment from vertex and extend it towards point H, so it forms a line segment GH. The H must be on the same plane but situated on the same side of point F and I.
Suppose the angle FGI is 80°. Then, if the angle bisector is drawn, two 40° angles are drawn: angle FGH and HGI. These angles are situated side by side together.
The answer is 75
First you subtract 180 and 165 to find that smallest angle inside the triangle(15). Then you add 15 and 90,the two angles you know, and do 180 - 105= 75.
The trick is that all angles inside a triangle equal 180 degrees. Hope this helps!
Answer:
−7.6n+9.7
Step-by-step explanation:
First, lets put the equation
≈3.7 - 4.6n - 3n + 6
Add light terms
−7.6n + 9.7
