Answer:
C. 7
Step-by-step explanation:
4 * Sum (i = 1 to 3) (1/2)^(i - 1) =
= 4 * [(1/2)^0 + (1/2)^1 + (1/2)^2]
= 4 * [1 + 1/2 + 1/4]
= 4 * [7/4]
= 7
Answer:
The correct answer is option 1. cubic units.
Step-by-step explanation:
The formula for the volume, V of a right angled cone is given as:
Where,
is the radius of the circular base of the cone.
is the height of the cone.
We are given that height is twice of the radius of its base.
Let the radius of base = units
Now, As per the question statement,
The height of cone= units
Putting the values of in equation (1) to find the volume:
Hence, the correct answer is option 1. cubic units.
Answer:
43
Step-by-step explanation:
Vertically opposite angles.
Here,
b=43 (being vertically opposite angles )
Answer:
a)
The point that is equidistant to all sides of a triangle is called the <u>incenter</u>.
The incenter is located at the intersection of bisectors of the interior angles of a triangle.
b)
The point that is equidistant to all vertices of a triangle is called the <u>circumcenter</u>.
The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.
c)
<em>See the attachment</em>
The blue lines and their intersection shows the incenter.
The red lines and their intersection shows the circumcenter.
As we see the red point- the <u>circumcenter </u>is closer to vertex B.
