Answer:
shaded area = 8.7 ft²
Step-by-step explanation:
area of circle = πr² = (3.14)(4²) = 50.24 ft²
apothem of hexagon = (sin 60° x 4) = 3.464
area of hexagon = 1/2(3.464)(6)(4) = 41.56 ft²
50.24 - 41.56 = 8.68 ft²
If I understood your post correctly, then this will be the equation we evaluate: (6-2)!
We can simplify this to: 4!
4! = 4 x 3 x 2 x 1 = 24
Answer:
(2y + 22) years
Step-by-step explanation:
kamau is now 2 years older than Jane if Janes age is y now what will be the total age in 10 years.
Answer: If Jane is y years old now and Kamau is 2 years older than Jane, therefore the age of Kamau now would be 2 + y years.
In ten years time Jane age would be y + 10 years while the age of Kamau would be y + 2 + 10 = y + 12 years.
To get their total age we just have to add their individual age. Therefore the total age in 10 years = Age of Kamau in ten years + age of Jane in ten years = (y + 12) + (y + 10) = y + 12 + y + 10 = y + y + 12 + 10 = 2y + 22 years
Add 3x to both sides of the equation which means y=13+3x
Answer: 4.6 km
Step-by-step explanation:
a^1 + b^2 = c^2
2^2 + b^2 = 5^2
4 + b^2 = 25
b = sqrt 25 - 4
b = sqrt 21 = 4.6 km
