Hello :
the circumference of a circle is P : P = <span>2π×r r : ridus
</span> P = 2π×r = π× L because : 2r = L
you can find the diameter L : L = P/π
53.75.....the 7 is in the tenths place....its value is 7/10

Answer:
A -> E
B -> D
C -> F
Step-by-step explanation:
In all cases, we represent minutes that Christopher has read with variable x
Christopher has read for more than 32 minutes corresponds with the inequality: x > 32
."More than" is equivalent to "greater than", which is symbolized by ">".
Christopher has read for less than 32 minutes, corresponds with the inequality: x < 32
. "Less than" symbolized by "<".
Christopher has read for 32 minutes corresponds with the equality: X = 32. Here the amount of time is fixed, so it agrees with an equality instead of an inequality.
Area = 24*Pi ft²
Area = Pi*r²
Pi*r² = 24*Pi
Canceling out Pi
r² = 24
Take square root of both sides
r = √24
r ≈ 4.899
Circumference = 2*pi*r
≈ 2*pi*4.899
≈ 2*3.141*4.899
≈ 30.78
Circumference ≈ 30.78 units.
Hope this explains it.
