Answer:
552.920307 yd^2 or 552.92 yd^2 for sigfigs
Step-by-step explanation:
basically you take the area of the entire circle and subtract the interior circle to leave the ring and that’s your answer
so the area formula of a circle is π r^2
the radius (r) is just half the diameter so the entire diameter is 48 so the radius is 24 - π(24)^2 = 1809.557368^2
then the interior circle’s diameter is 40 so the radius is 20 - π(20)^2 = 1256.637061^2
so now it’s just subtraction:
1809.557368 yd^2 - 1256.637061 yd^2 =
552.920307 yd^2 or 552.92 yd^2 for sigfigs

Answer:
x=20
Step-by-step explanation:
(4x-12)+(x+2)=90
5x-10=90
5x=100
x=20
Answer:
x > 9/20
Step-by-step explanation:
4/5 + x + 1 > 9/4
multiply both sides by 20 to eliminate the fractions
16 + 20x + 20 => 45
Combine like terms
20x + 36 > 45
Subtract 36 from both sides
20x > 9
Divide both sides by 20
x > 9/20
