Answer:
50.29 in^2
Step-by-step explanation:
From the circumference we need to find the radius.
Since C = 2*pi*r, r = C / (2*pi).
Here, with C = 25 1/7 in, r = (25 1/7 in) / [ 2(22/7) ], or r = 4 in
The area of the cake is A = pi*r^2, or (here) A = (22/7)(4 in)^2 = 50.29 in^2
Answer: See below
Explanation:
Write an equation for nth term:
a + d(n - 1)
a = 8 (first term)
d = -6 (common difference)
8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14
Find a 50:
-6(50) + 14
= -300 + 14
= -286
When you divide 52 by 8, you have to find the nearest multiple of 8 that is either equal to or less than 52.
closest multiple of 8 that is less than 52 is 48. Quotient is the number of times 8 is in 48. In other words 8 is there 6 times in 48.
quotient is found by dividing the closest multiple of 8 (48) by 8.
48 / 8 = 6
quotient is 6
remainder is the difference between the number given and closest multiple
number given is 52. closest multiple is 48. difference between 52 and 48 is
52 - 48 = 4
the remainder is 4
quotient is 6
160/4 = p/6
Cross-multiply the propportion:
160 x 6 = 4p
Divide each side by 4:
p = 40 x 6 = 240 pages
