Answer:
3.14 or pi
Step-by-step explanation:
the area of a circle =
where r is the radius of the circle
this is 1/4 of the circle, so it would be 1/4 (pi * r²)
it shows that the radius is 2, so you have
1/4 ( pi * 2²)
= 1/4 ( pi * 4 )
= 1/4 (3.14 * 4)
= 3.14 units²
Is -1.393 the significance level and if so what’s the degree of freedom?
Answer:
35
Step-by-step explanation:
sin is opposite over hypotenuse

Answer:
240
Step-by-step explanation:
First start with the inner most bracket
20 - 6 = 14
Then solve the next bracket
14 + 1 = 15
Then the next
15 x 8 = 120
Then divide by a half (times by 2)
120 / 0.5 = 240
