Step-by-step explanation:
Answer:
Step-by-step explanation:
28. Area of the circle = π
where r is the radius of the circle.
Given diameter = 14m, therefore radius =
= 7m
Now area of the circle = 49
or = 49 * 3.14 * 3.14 = 483.12
29. Volume of cylinder = π
h = π*
* 3 = 6.75π cu. feet or 21.195 cu. feet
30. A ball resembles a sphere. Volume of the sphere = 
Given diameter = 30inches; Therefore, radius = 15 inches
Now, Volume of the ball =
= 4500π cu. inches or 14310 cu.inches
Answer:
Step-by-step explanation:
Each parrot gets 2 grapes in one day
In total: Lena gives her parrots(ALL FIVE OF THEM) 10 grapes all together
This is a square matrix whose entries are real and rows and columns are orthogonal unit vectors.
8 x .75 x 1.50 = 9 that is your answer
