Answer: 423.11 m^2
Step by step explanation:
Area of a circle formula pi*r^2
First solve the area of the big circle
3.14*21^2=1384.74 m^2
Now find the are of the smaller circle
r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2
Now we can minus the small area off the big area to get the shaded area.
1384.74-961.63=423.11 m^2
So the area of the shaded region is 423.11 m^2

5
Step-by-step explanation:
9x+6y=-3
9x+6(-8)=-3
9x-48=-3
9x=45
x=5
Answer:
(x-4)^2 + (y+5)^2 = 324
Step-by-step explanation:
The equation of a circle is given by the equation (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center point of the circle.
Therefore, since the center point of the circle and the radius is given, we can just plug the numbers into the formula:
(x-4)^2 + (y+5)^2 = 18^2
<u>(x-4)^2 + (y+5)^2 = 324</u>
Answer:
26
Step-by-step explanation:
because look at the tail
Let's solve your equation step-by-step.
25812−4.2d=31.311−5.5d
Step 1: Simplify both sides of the equation.
25812−4.2d=31.311−5.5d
25812+−4.2d=31.311+−5.5d
−4.2d+25812=−5.5d+31.311
Step 2: Add 5.5d to both sides.
−4.2d+25812+5.5d=−5.5d+31.311+5.5d
1.3d+25812=31.311
Step 3: Subtract 25812 from both sides.
1.3d+25812−25812=31.311−25812
1.3d=−25780.689
Step 4: Divide both sides by 1.3.
1.3d
1.3
=
−25780.689
1.3
