The diagram shows the cross section of a solid metal prism of height 32 cm.
AD = 8.7 cm, AC = 8cm, AB =
8cm, AB = 6.4cm, BC = 4.8cm and CD = 3.3cm.
The prism is melted down and recast as five identical cylinders, each of
height 10 cm.
Calculate the base radius of each cylinder to 2DP
Type each step of your working on a separate line

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
