5:2:1
If the shortest piece, 1, is 120cm, just multiply it by 2, then 5
120 x 2 = 240cm (the 2 in 5:2:1)
120 x 5 = 600cm (the 5 in 5:2:1)
Answer:
41.8887 cm^2
Step-by-step explanation:
area of a circle
A = pi * r^2
A = pi * (3 + 4)^2
A = pi * 49
A = 153.94
120 / 360 = 1/3
153.94 / 3 = 51.3134
now area of inner circle
A = pi * 3^2
A = pi * 9
A = 28.274
28.274 / 3 = 9.4247
subtract
51.3134 - 9.4247 = 41.8887
Answer:
He ate 42 of the 90 grapes in the bowl
The percentage of grape he ate will be given as this:
42/90 * 100%
=46.67%
Tyler has ate 46.67% of the grapes

use Pythagorean Theorem to satisfy...a^2 + b^2 = c^2
200^2 + b^2 = 300^2
b^2 = 300^2 - 200^2
b^2 = 50000 (get square root of each)
b = 223.606 (rounded to the nearest tenth.... = 223.6
The answer equals 14
2*7
(r=square root of 49)
