Answer:
Step-by-step explanation:
step 1
Find the area of complete circle
The area of the circle is given by the formula
we have
substitute
step 2
Find the area of the shaded region
we know that
The area of complete circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of the shaded region if the central angle is equal to 80 degrees
Order the numbers from smallest to largest: 1.448, 2 , 14 10 , and 1.22, A) 14 10 , 2 , 1.22, 1.448 B) 14 10 , 1.22, 1.448, 2 C)

Answer:
1.448 - 1.22 - 2 - 1,410
Step-by-step explanation:
smallest ------ Largest
2ab x cos (C) = 7 because
a^2 + b^2 - 2ab x cos(C) = c^2
2ab x cos(C) = a^2 + b^2 - c^2
2ab x cos(C) = 2^2 + 2^2 - 1^2
2ab x cos (C) = 7
Answer:
1 . Closure
2. Distributive
3. Closure
Step-by-step explanation:
Here, we want to know the type of property exhibited or displayed by each of the equations in the question.
Equation 1 displays the closure property.
What this means that if we make an addition operation either way, we would get same answer. So we say that addition is closed for that equation.
Equation 3 exhibits closure property as well. If we go either way on the addition operation for that equation, we are bound to get the same answer.
Equation 2 exhibits the distributive property.
Each term in the bracket is multiplied by the subtraction symbol before we proceeded to complete the arithmetic operations
