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
72 × 1.4666666666667 = 105.6 feet per second
8x+4=9x-5
when you solve that out you get x =9
then you plug in x everywhere in the chart
3(9)=27
9(9)-5=76
180-76-27= 77°
angle E =77°

Answer:
He messed up on x + 2 = 5 (when he divided both sides by 3.)
He is first supposed to subtract 2 from both sides and you would get 13. Then you would divide both sides by 3 which would get you 4.33 repeating.
Answer:
2.5 = X
Step-by-step explanation:
2.5^3 = 15.7 rounded up to 16
2 + 16 = 18
have a nice day and mark me brainliest! :)
