Area of a cirlce=πr²
we have two radius:2r and r
area of the cirlce₁ + area of the circle₂=80 m²
area of the circle₁=π(2r)²
area of the circle₂=πr²
Then, we can suggest this quation:
π(2r)²+πr²=80
4πr²+πr²=80
π(4r²+r²)=80
π(5r²)=80
5πr²=80
r²=80/5π
r=√(80/5π)≈2.26
radius of the largest cirlce=2r=2(2.26)=4.51
Answer: the radius of the largest circle is 4.51 m
Answer:
that already is a decimal
Step-by-step explanation:
the fraction form of it is 12 and 1/2
the decimal version of that it 12.5
So we’re already know the area of but not the width so to find the area of the rectangle
Area= LxW
So the length is 3/7ft and the area is 2
2= 3/7 x W
W is a missing number
So to find the area multiply l x w right? So we have to reverse it by
2 divided 3/7= 14/3
So the width is 14/3
Check
3/7 x 14/3 = 2
Hope this help?
