Answer:
7.1%
Step-by-step explanation:
The formula for percentage relative change =
[Final value - Initial value/Initial value] × 100
From the above question
Initial value = 42 %
Final value = 45%
= 45 - 42/ 42 × 100
= 3/42 × 100
= 7.1428571429 %
Therefore, approximately to the nearest tenth, the percentage relative change = 7.1%
Answer:
CSA of cylinder= 2πr(h+r)
=2 π×9 (21)
= 378π cm²
now
CSA of hole= 2πr
12π cm²
What is the net of the shape? I would say a ball, or a cylinder.
