Step-by-step explanation:
there is a right ∆ and a sector
area of right ∆ = .5×6×5 = 15 cm^2
area of sector = angle/360 * π * r^2
= 1/4 * π * 25 = 19.63 cm^2
area of the shape = 34.63 cm^2
Answer:
20
Step-by-step explanation:
Given: F = 11, C = 11, E=?
By Euler's formula, we have:
Hence, the solid will have 20 edges.
The first term in our arithmetic sequence = 13
The common difference of our arithmetic sequence = 17 - 13 = 4
The formula for finding an equation for any arithmetic sequence is a(n) = A + B(n - 1)
A = the first term
B = the common difference.
Let's plug our numbers in.
a(n) = 13 + 4(n - 1)
Let's check to make sure we're correct.
a(1) = 13 + 4(1 - 1) = 13 + 4(0) = 13 + 0 = 13
a(2) = 13 + 4(2 - 1) = 13 + 4(1) = 13 + 4 = 17
That verifies that our formula is correct.
In conclusion,
a(n) = 13 + 4(n - 1)
Ab means A multiplied by B.
Now, let's say Ab is 1*2
Then ba would be 2*1
So yes, they're technically the same. Just in a different order.
