Answer:
6
Step-by-step explanation:
A = pi r^2
C = 2 pi r
A = B (area)
3C = B
sub C = 2 pi r into 3C = B, and A = pi r ^ 2 into B
3 (2 pi r) = pi r ^ 2
6 pi r = pi r^2
( divide both sides by pi )
6r = r^2
r^2 - 6r = 0
r(r-6) = 0
r = 0 or r-6 = 0
radius can not be 0 , therefore r = 6
hope this makes sense, might be little confusing sorry!
Answer:
8 times
Step-by-step explanation:
Given
The attached histogram
Required
The number of times the team gain at least 6 yards
From the question, the entry that fall in the category of at least 6 yards are:
, 
and 
Their frequencies are:
5, 2 and 1 respectively
So, the number of times is:
<span>7 29/80 as a decimal is 7.3625. First, turn it into an improper fraction: to work out the numerator, add the current numerator (29) to the 7 whole 80ths represented by the integer of the mixed number. (7 x 80) + 29 = 589. 589/80 cannot be cancelled down. As a decimal it is 7.3625.</span>
