Answer:6.05cm
Step-by-step explanation:
Circumference=2×π×r
38=2×22/7×r
38×7=2×22×r
266=44r
r=266/44
r=6.05cm
Answer:
height = 7 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated using the formula
A = 
h(a + b)
where h is the height and a, b the parallel bases
here a = 6, b = 12 and A = 63, hence
× h × (6 + 12) = 63
h × 18 = 63
9h = 63 ( divide both sides by 9 )
h = 7
Answer:
There's one 0.
Step-by-step explanation:
Because I multiplied it and there's only one 0.
Cos Z = 32/40 => Z= cos-¹(32/40) =>
sin Z = sin (cos-¹(32/40)) = 3/5
Answer:
Blue: 2/3
Purple: 1/3
Step-by-step explanation:
You have a total of 3 possible sections.
For blue, we have 2 out of 3 sections. The probability is 2/3.
For purple, we have 1 out of 3 sections. The probability is 1/3.
