Answer:
The cross section will be an isosceles triangle
Step-by-step explanation:
The picture of the question in the attached figure N 1
we know that
If a plane passes through the axis of rotation of the cone, then the resultant cross-section will be a triangle with one vertex as the vertex of the cone and the two sides of the triangle through the vertex A will be equal.
Where the base of the triangle will be equal to the diameter of the circular base of cone and the two congruent sides of triangle will be equal to the slant height of the cone
therefore
The cross section will be an isosceles triangle
Answer:
72
Step-by-step explanation:
I’m guessing 108. 45 divided by 5 is 9, so 9 times 12 is 108.
Answer:
Step-by-step explanation:
A circle is divided into 8 equal parts means : 360°/8 = 45°
the total angle measure of 4 parts is :
45°×4=180°
