Find the radius of a circle in which a central angle of StartFraction pi Over 7 EndFraction radian determines a sector of area 7
QveST [7]

Answer:

Step-by-step explanation:

The formula for determining the the area of a sector is expressed as

Area of Sector = θ/360 × πr²

Where

θ represents the central angle.

π is a constant whose value is 3.14

r represents the radius of the circle.

From the information given,

The central angle is π/7 radian. Converting to degrees, it becomes

π/7 × 180/π = 180/7 = 25.714 degrees.

Area of sector = 77 square meters

Therefore

77 = 25.714/360 × 3.14 × r²

77 = 0.2243r²

r² = 77/0.2243 = 343.29

r = √343.29 = 18.53 meters

How to solve 4k-1.5k=50
padilas [110]
Combine like terms-- you can combine the k's:
4k-1.5k=2.5k

Now you have:
2.5k=50

Simply divide both sides by 2.5 to find the value of k:
\frac{2.5k}{2.5}=\frac{50}{2.5}\\\\k=20
