Answer:
141.4 sq cm
Step-by-step explanation:
to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger
the radius of the smaller circle is 2
we have to find the radius of the larger circle so we use what we know about its circumference:
C = 2πr
43.96 = 2πr
21.98 = πr
21.98 / π = r
r ≈ 7 cm
now use r = 7 to find area of larger circle:
A = πr²
A = π49
Area of smaller circle: 4π
Area of larger circle without including inner section is 49π - 4π = 45π
45π ≈ 141.4 sq cm
L + F + G = 51
F = 3L...F = 3(G + 4)....F = 3G + 12
L = G + 4
(G + 4) + (3G + 12) + G = 51
5G + 16 = 51
5G = 51 - 16
5G = 35
G = 35/5
G = 7 <=== Greg sold 7
L = G + 4...L = 7 + 4....L = 11 <== Lin sold 11
F = 3G + 12.....F = 3(7) + 21....F = 21 + 12....F = 33 <== Fran sold 33
Answer:
{Japan: $25.93} {Switzerland: $22.05}
Step-by-step explanation:
It's simple to solve for Japan but for Switzerland you got to do some reverse math.
For Japan all you gotta do is divide the given total by three because you're finding how much <u>one</u> ticket costs and not three. so there you have $25.93
For Switzerland here comes the reverse math. you have to take your $25.93 times 2 because is says "plus two tickets in Japan" so you have $51.86
Now that you've figured out the total of two tickets in Japan, you can subtract that from the given total ($73.91) and the answer is $22.05
