that would be the circumference of the circle
= 2 pi r
= 2 * pi * 2
= 6.28 feet to 2 DP's.
It’s b. Because the number with out the x is the y-interact which is -2 then to find the other number I look at the graph and find another point and then count the rise/run which is rising 2 running 3 and it’s also positive that’s why it’s b.
5m-3h=45
/5 = /5
m-3h=9
-3 = -3
m+h=6
-m = -m
h=6-m
bro i literally had the same question about this
you in honors or something? sry i only got A
I might have B later on or something
Answer:
A.
41.125π ≈ 129
149.875π ≈ 471
Step-by-step explanation:
Surface area of smaller ganza:
3.5/2 = 1.75 x 1.75 = 3.0625 x 3.14 = 9.61625 x 2 = 19.2325
1.75 x 10 = 17.5 x 3.14 = 54.95 x 2 = 109.9 + 19.2 = 129 (Rounded)
Surface area of larger ganza:
5.5/2=2.75 x 2.75 = 7.5625 x 3.14 = 23.74625 x 2 = 47.4925
2.75 x 24.5 = 67.375 x 3.14 = 211.5575 x 2 = 423.115 + 47.4925 = 471 (Rounded)
π
129/3.14 = 41.125
471/3.14 = 149.875
