125.6
Area of a circle = πr^2
Area of circle 1 = 3.14 × 11 × 11
=379.94cm^2
Area of circle 2= 3.14 × 9 ×9
=254.64cm^2
Area of a shaded region
=379.94cm^2 - 254.64cm^2
=125.60cm^2
Answer:
A=5
Step-by-step explanation:
5-3a<-10 is the same as
5-3a=-10
So to solve it just solve for a.
subtract 5 from both sides
-3a=-15
dived -3 from both sides to get a alone
A=5
hope this helps!
Answer:
4π
Step-by-step explanation:
We are asked to calculate the area of a circle whose diameter is equal to 4, we know that the area of the circle is given by the following equation:
A = π * (r ^ 2)
where r is the radius of the circle, we know that the radius of the circle is half the diameter, therefore:
r = d / 2 = 4/2
r = 2
replacing, we are left with:
A = π * (2 ^ 2)
A = 4π
Which means that the area of the circle is 4π
Answer:
M and P
Step-by-step explanation:
they do not cross each other
-4/2 which simplifies to -2/1
