Answer:
The radius of the circle is approximately 14.42cm
Step-by-step explanation:
If the length of the chord is 16cm and it is 12cm from the center of the circle.
it means it forms 2 right angles while dividing the center of the chord, to the center of the circle, and at right angle. Length of the adjacent then become 16/2 = 8cm
To calculate the radius which forms hypothenus of the right angle triangle, we use Pytagoras Theorem
Say = + , where r is the radius of the circle
= 144 + 64
= 208
r =
r = 14.4222
r ≈ 14.42
Answer:
5a + 2b
Step-by-step explanation:
9a + 3b -4a -b
9a - 4a + 3b - b
5a + 2b
B is the answer to this question
Step-by-step explanation:
W = (2L -57)
P = 2×(L+W)
198 = 2× (L + 2L -57)
198 = 2× (3L - 57)
3L-57 = 198/2
3L-57 = 99
3L = 99+57
3L = 156
L = 156/3 = 52
W = 2(52) -57 = 104-57 = 47
so, the length = 52 ft
and the width = 47 ft
