The answer really depends on what b is. Unless you give me a number for what b equals I can’t solve it.
Upper quartile would be 4.5. The interquartile range could be 6.
Answer:
Step-by-step explanation:
cos 225 = -cos 45 = -1/√2.
sin 225 = -sin45 = -1√2.
Answer:
C
Step-by-step explanation:
The circumference (C) of a circle = 2πr ← r is the radius
Given C = 15π the equating gives
2πr = 15π ( divide both sides by 2π )
r =
= 7.5 cm
The area (A) of a circle is calculated using the formula
A = πr² = π × 7.5² = 56.25π cm² → C
we need to know the height the length and the width
