Yes, EF is parallel to CD. Translation is the simple slide of a shape, therefore it doesn't have an effect on parallel lines.
        
                    
             
        
        
        
Answer:
30m
Step-by-step explanation:
A=πr²
225π=πr²
225=r²
r=√225
r=15
d=2r
d=2×15
=30m
 
        
             
        
        
        
Answer:
246 in^2
Step-by-step explanation:
Given data
Length= 8 in
Width= 3 in
Height= 9 in
SA= 2( lw + wh + hl)
substitute
SA= 2(8*3+ 3*9+ 9*8)
SA= 2(24+ 27+72)
SA= 2(123)
SA= 246 in^2
Hence the SA is 246 in^2

Hello from MrBillDoesMath!
Answer:
225
Discussion:
Sum ( 2n - 1)                  from  n = 1 to 15              
= Sum(2n) - Sum(1)        from n = 1 to 15
= 2 Sum(n) - Sum(1)       from n = 1 to 15
= 2* 15(15+1)/2  - (1 + 1 + .. + 1)
The first value comes from the fact that the sum of the first n integers is  n(n+1)/2. The latter value sums 15 1's.
= 2 * 15 * 16/2 - 15                    => 2/2 = 1
= 15*16 - 15                               => 15*16 = 240
= 240 - 15
= 225
Thank you,
MrB
