Given:
Radius of the circle = 10 in
Central angle of the sector = 45 degrees
To find:
The area of the sector.
Solution:
Area of a sector is
Where, 
is the central angle in degrees.
Putting r=10 and 
, we get
Therefore, the area of the sector is 12.5π sq. inches.
8x+9-4x=25
4x+9=25
4x+9-9=25-9
4x=16
4x/4=16/4
X=4
68*x/100=48
=> 68*x=4800
=> x=4800/68
=> x~=70.58
P.S: * means multiply, ~= means approximation, / means divide
The magnitude size of -5.8 is 5.8
magnitude size of a number is the number itself, and if it’s negative, it becomes its absolute value (in other words, you remove the subtraction sign).
Answer:
Step-by-step explanation:
v=3p(w-r)
v=3pw-3pr
v+3pr=3pw
(v+3pr)/3p=w
