Answer:
The answer would be D. 14 cm block
Step-by-step explanation:
if you count all the blocks the you get 14. this is the total number of cm blocks.
each block is 1 cm³ and the figure has
bottom layer (2*3)cubes = 6 cubes
second layer (2*3)cubes = 6 cubes
third layer from down to up has 2 cubes
In all we have 6+6+2 = 14 cubes
V = 1cm³ * 14 cubes = 14 cm³
80.64
12.6*6.4=80.64
C
r=14cm
Curved Surface area of a cylinder=484cm²
Height=5.5cm
r=?
Curved Surface Area=2πrh
484=2×3.142×r×5.5
484=34.56r
r=484/34.56
