Answer:
or 
Step-by-step explanation:
The volume of a cylinder is calculated by the following formula

Where r is the radius of the cylinder and h is the height
In this case we know that the radius r of the base is:

and

So the Volume is:



Answer:
10a: △ABC is an Equilateral triangle with all acute angles.
10b: △BCD is A scalene triangle with all acute angles.
10c: △BDE is An Isosceles triangle with one obtuse angle.
Step-by-step explanation:
10) Looking at the diagram at the bottom left;
- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.
Thus, we can classify it as; Equilateral triangle with all acute angles.
- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.
We can classify it as;
A scalene triangle with all acute angles
- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.
Thus, we can classify it as;
- An Isosceles triangle with one obtuse angle.
Answer:
1000 cm²
Step-by-step explanation:
Given:
- Length = 10 cm
- Width = 12.5 cm
- Height = 8 cm
<u>Formula:</u>

Substitute the length, width, and the height of the prism to determine the volume of the prism.

Simplify the right hand side of the equation, as needed;



Therefore, the volume of the prism is 1000 cm².
Answer:
A.18/25
B.72% of them brought in their permission slips
C.0.72
D.There the exact same value and we would divide by 100 to go from percentage to decimal and multiply by 100 to go to decimal to percentage Sign.
Step-by-step explanation:
% means 'parts out of 100' so
25%=25/100
is 12 is 25 parts out of 100 of a number
so 12=(25/100)x
25/100 simplifies to 1/4
or if 12=(1/4)x
we multiply both sides by 4 and get
48=1x
