the sum of areas of two circles is 80 square meters find the lencgh of radius of each circles if one of them is twice as larger
klemol [59]
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

Can anyone help me with this math problem?
Vika [28.1K]
\bold{FULL ANSWERS:}

In 1993, Moose Population: 3280

In 1999, population became: 4960

P (Population) , t (years)

t = 6 —> 4960 - 3280 = 1680

Average Change —> 1680/6 = 280 moose/year

• In terms of 1990:

t = 3 —> 3280-3 (280)

P(1990) = 2440

P(t) = 2440 + 280t

• In 2003; t = 13

P(13) = 2440 + 280 (13)
P(13) = 2440 + 3640
P(13) = 6080

• Moose population in 2003

= 6080
