Answer:
See below.
Step-by-step explanation:
Area of outer circle = π R^2
and area of the inner circle = π r^2 so the area of the ring
= π (R^2 - r^2) (Equation (1) ).
Consider the triangle OBC. We have, by Pythagoras, R^2 = r^2 + BC^2.
So BC^2 = R^2 - r^2.
Substituting for R^2 - r^2 in equation (1):
Area of the ring =<u> </u><u>π BC^2 </u> as required.
Answer:
if broccoli is green then it is a vegetable
if the broccoli we observe is green then it is a vegetable
All of the broccoli we observed were green so therefore we can conclude that they are vegetables
The vegetable is broccoli if it is green
yes, the vegetable is broccoli if it has a stem
If the broccoli is not green then it is not a vegetable
yes, If the broccoli does not have a stem then it is not a vegetable
(sorry that's all i know how to do.)
Answer:
Step-by-step explanation:
X = 4,0
hypotenuse = sqrt(4^2 + (-sqrt(33))^2 )
hypotenuse = sqrt(16 + 33)
hypotenuse = sqrt(49)
hypotenuse = 7
Cos(theta) = 4/ 7
The cos looks like it should be negative, but it is positive in quad 4.
