C = 14π cm ( in terms of π )
the circumference (C) of a circle is calculated using the formula
C = πd ( where d is the diameter )
C = 14π cm ≈ 3.14 × 14 - 43.96 cm
Answer:
b)
{t | –3 < t ≤ 5}
Step-by-step explanation:
–4 < 3t + 5 ≤ 20
⇔
-4 - 5 < 3t ≤ 15
⇔
-9 < 3t ≤ 15
⇔
-3 < t ≤ 5
Answer:
10 pieces
Step-by-step explanation:
divide the total length by length of each pieces
2.5/0.25
The answer is 35563.84x²-6042.4x
72 - 55 = 17
(17/55) x 100
= 1700/55
= 30.90909...
= 30.9% (3sf)
