Answer:
Step-by-step explanation:
Given the circumference of Circle K = π
circumference of Circle L = 4π
Ratio of their circumferences = Ck/Cl
Ratio of their circumferences = π/4π
Ratio of their circumferences = 1/4 = 1:4
For their radii
C = 2πr
for circle k with circumference π
π = 2πrk
1 = 2rk
rk = 1/2
for circle l with circumference 4π
4π = 2πr
4 = 2r
r = 4/2
rl = 2
ratio
rk/rl = 1/2/2
rk/rl = 1/4 = 1:4
for the areas
Area of a circle = πr²
for circle k
Ak = π(1/2)²
Ak = π(1/4)
Ak = π/4
for circle l
Al = π(2)²
Al = 4π
Ratio of their areas
Ak/Al = π/4/(4π)
Ak/Al = π/16π
Ak/Al = 1/16 = 1:16
Wait, this is simplified because there are no common terms.
Oof this one is hard I think it’s 20 mm but I’m not sure

Answer:
Step-by-step explanation:
<u>Perimeter of garden A is
</u>
- P = 2(w + l) = 2( 2x - 3 + 5(2x - 3)) = 24x - 36
<u>Perimeter of garden B is
</u>
-
5x + 5 + 4x + 2 + 8x - 8 = 17x - 1
<u>Sum of perimeters:</u>
- 24x - 36 + 17x - 1 = 41x - 37
The statement 2 is FALSE as number we got is different from the one in the statement
