B.(37.68 in2)
C.(1808.64 in2)
D.(452.16 in2)
Circumference = diameter x pi
Find the diameter:
75.36 = diameter x pi
Divide both sides by pi:
Diameter = 75.36/3.14 = 24 inches.
Area = pi x r^2
R = 1/2 diameter = 12
Area = 3.14 x 12^2
Area = 452.16 in^2
The answer is D.
Answer:
x = 25/3
Step-by-step explanation:
2x-5=20-x
2x-5+5=x+20+5 (add 5 both to both sides)
2x = -x + 25
2x + x = -x + x + 25 (add x to both sides)
3x = 25
3x/3 = 25/3 (divide both sides by 3)
x = 25/3
Applying the rule that a number is divisible by 9 if the sum of its digits is divisible by 9, we find that 504 and 882 from the list (115, 504, 968, 646, 882) are divisible by 9.
To identify numbers that are divisible by 9, we can follow this rule: A number is divisible by 9 if the sum of its digits is divisible by 9. So, applying this rule to the numbers given (115, 504, 968, 646, 882), we find:
115: 1+1+5 = 7, which is not divisible by 9.
504: 5+0+4 = 9, which is divisible by 9. So 504 is divisible by 9.
968: 9+6+8 = 23, which is not divisible by 9.
646: 6+4+6 = 16, which is not divisible by 9.
882: 8+8+2 = 18, which is divisible by 9. So 882 is divisible by 9.

Answer:
Step-by-step explanation:
4(x+1)²=100
(x+1)²= 5²
(x+1)²- 5² = 0
(x+1-5)(x+1+5) = 0 by identity : a² - b ² = (a - b) (a+b)
(x - 4 ) (x+6) =0
x - 4 = 0 or x+6 = 0
x = 4 or x = - 6
