(1) circumference of a circle = 2π.R
(2) area of a circle = π.R²
Area = 452.16 m² (given), so we can calculate the radius:
452.16 = π.R²
452.16/π = R²
143.92 = R² → R =√143.92 ≈ 12 m
Having R = 12, now we can calculate the circumference :
circumference of a circle = 2π.R = 2.π.12 = 75.41 m
Given that sandwiches are made with either turkey or ham.
Prob for turkey or ham = 1/2
The fruit can be either apple or orange. Hence p(apple) = p(orange) =12
Drinks can be either bottled water or juice
P(water) = P(juice) = 1/2
We find that sandwiches, fruits, and drinks are mutually independent of each other.
Hence the probability you will get an orange and not get juice in your box
Prob (you get an orange and bottled water)
= Prob (orange) *Prob (bottled water) (since the two are independent
= 1/2 (1/2)= 1/4
Hence answer is 0.25
It increased by 7.7 degreese because it goes from -16.5 to -8.8. You would have to subtract 8.8 from 16.5 but it is easier to make them positive.
Oooh I miss these. Haven't done them since kindergarten! 24/25 would equal 0.96. 87+0.96 would get 87.96. 7/10 is 0.7 so 224+0.7=224.7. 49/50 is 0.98, so 0.98+686 is 686.98.
Consider the bottom most rectangle.
Its length = 5 - 2 = 3 units
Its width = 3 - 1 = 2 units
So, its area = 3(2) = 6 square units.
Consider the middle rectangle.
Its length = 2 - 1 = 1 unit
Its width = 4 - 2 = 2 units
So, its area = 1(2) = 2 square units.
Finally, consider the top rectangle.
Its length = 6 - 1 = 5 units
Its width = 6 - 4 = 2 units
Its area = 5(2) = 10 square units.
Hence, total area = 6 + 2 + 10 = 18 square units. Correct option is C.
