Step-by-step explanation:
Easy people kinda hard to be honest
Answer:
True.
Here, radius of the sphere = radius of the cylinder = r
Diameter of the sphere = height of the cylinder = 2r
Surface area of the sphere = 4πr2
Curved surface area of the cylinder = 2πr (2r) = 4πr2
Step-by-step explanation:
Answer:
sum of the polynomials is 
Step-by-step explanation:
Given polynomial is (7 x^3– 4 x^2) + (2 x^3 +3 x)
adding x^3 terms, now we get


Therefore the sum of given polynomial is

I believe it is A. hope this helps
Construct two angle bisectors of the triangle
Answer:
Option (D) is correct
<u>Step-by-step explanation:</u>
We have to contruct two angle bisectors of the triangle.
various steps to inscribe the circle in a triangle are
- First draw a triangle
- Draw angle bisector of one angle
- Draw angle bisector of another angle
- Extent these angle bisectors, where they meet that point will be called the incenter
- From incenter draw prependicular to any side of the triangle
- The length from the point where the prependicular touches the side of triangle to the point of incenter will be radius.
- Use this radius and draw the incircle.
