A cylinder with base area 25 pi cm squared and height 3 cm more than the radius
Alina [70]
The correct question is 
Find the volume of a <span>cylinder with base area 25 pi cm squared and height 3 cm more than the radius

we know that
</span>[the volume of a cylinder]=[area of the base]*[height]
[area of the base]=25pi cm²
[area of the base]=pi*r²--------> r²=[area of the base]/pi----> r²=25pi/pi
r²=25--------> r=5 cm

the height is 3 cm more than the radius
so
height=3+5-----> height=8 cm

[the volume of a cylinder]=[25pi]*[8]------> 200pi cm³

the answer is
200pi cm³

Name the property shown by the statement. (8 + 7) + 3 = 8 + (7 + 3)
Evgen [1.6K]

Step-by-step explanation:

Associative Property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped', I mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Example: 3+(2-4) can be rewritten as (3+2)-4.

hope it helps!
