Answer:
-3/1 and -2/1
Step-by-step explanation:
Answer:
Step-by-step explanation:
The area of the base is given by the formula ...
A = πr²
so the radius is ...
r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units
__
The volume is given by ...
V = (1/3)Bh
where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...
V = (1/3)(1386)(21) = 9702 . . . . cubic units
The area of the figure is 30 because u have to add an subtract the numbers on the side
Answer:
(-9,-2)
x= -9
y= -2
Step-by-step explanation:
x+5y=-19
x-5y=1
solve the equation
x+5y=-19
x=1+5y
substitute the value of x into an equation
1+5y+5y=-19
add 5y to 5y
1+10y=-19
subtract 1 to -19
10y=-20
divide both sides by 10
y= -2
substitute the value of y into an equation
x=1+5•(-2)
multiply 5 to -2
1+-10
add 1 to -10 but since 10 is a negative the equation is subtraction.
x= -9
(-9,-2)
