Answer:

<u>Yes</u>

Step-by-step explanation:

<u>When there are 2 rows</u>

  • Number of erasers per row =  No. of erasers / No. of rows
  • Number of erasers per row = 18/2
  • Number of erasers per row = 9

<u>When there are 3 rows</u>

  • Number of erasers per row =  No. of erasers / No. of rows
  • Number of erasers per row = 18/3
  • Number of erasers per row = 6

<u>Therefore, there will be more erasers per row in 2 equal rows than in 3 equal rows.</u>

The circumference of a bowling ball is 8pi in. Find the surface area of the bowling ball. Express your answer in terms of pi.
MrRa [10]
Surface area of a sphere (3D solid's name for ball shaped object) is given by

SA = 4 \pi r^{2}

We do not know the radius of the sphere but we can work it out from the circumference 8 \pi

Circumference = 2 \pi r
8 \pi =2 \pi r
r= \frac{8 \pi }{4 \pi }=2

then
SA=4 \pi  (2)^{2} =16 \pi
