Answer:
The correct option is 30.6
Therefore,
Area of Sector is 30.6 units².
Step-by-step explanation:
Given:
Central angle = θ = 142°
Radius = r = 5 units
pi = 3.14
To Find:
Area of Sector = ?
Solution:
If the θ measured in degree then the Area of Sector is given as
Where r = radius, θ = Central angle
On substituting the values we get
Therefore,
Area of Sector is 30.6 units².
Umm.. and the question is
Answer:6
Step-by-step explanation:
Answer:
63
Step-by-step explanation:
Set up the proportion
(6x+3)/17 = (8x - 1)/21 Cross Multiply
21 * (6x + 3) = 17 (8x - 1) Remove the brackets
126x + 63 = 136x - 17 Subtract 126x from both sides
63 = 136x - 126x - 17 Combine
63 = 10x - 17 Add 17 to both sides
63 + 17 = 10x Combine the left
80 = 10 x Divide by 10
80/10 = x
x = 8
Now you want 8x - 1
8*8 - 1 = 63
Zero has one square root which is 0.
Negative numbers Don't have real aquare roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members or the irrational numbers. That means that they can't be written as the quotient of two integers.
