Answer:
sin 70 degrees = 0.9396, 0.9396*3 approximately equal to the 2.82cm one area is 6*2.82/2=8.46cm²
Step-by-step explanation:
- Known this square covers an area of 36 cm square, so its length is 6 cm.
- so, we know that the lower side of the triangle is six, half of it is 3 cm.
- We make a triangle, and then the Angle of the triangle is 70 degrees, so, we can use the sin is to use bottom neighborhood is sin70 degrees = hemline is present in addition to 3cm.

Answer:
Option A 
Step-by-step explanation:
The volume of a cone is:
The volume of a cylinder is:
Both figures have the same height h and the same radius r.
The volume of the cylinder
We want to find the volume of the cone.
Then, we find r and h:
We simplify.
Then the product of 
.
We substitute this in the cone formula and get:
