Answer:
1. = 3.143
2. Circumference
3. Area of the circle is 3850 .
ii. Circumference of the circle is 220 cm.
Step-by-step explanation:
The area, A, and the circumference, c, of a circle can be determined respectively by:
A =
C = 2r
where r is the radius of the circle.
1. the ratio of the circumference and diameter, D, of a circle is:
r =
so that,
C = 2
C = D
=
=
= 3.143
2. The distance around a circular region is known as it's circumference.
3. Given a circle of radius 35 cm, then:
A =
= x
= x 1225
= 22 x 175
A = 3850
Area of the circle is 3850 .
C = 2r
= 2 x x 35
= 2 x 22 x 5
= 220
C = 220 cm
Circumference of the circle is 220 cm.
Answer:
x= -2 or -3
Step-by-step explanation:
Let's solve your equation step-by-step.
x^2+5x+6=0
Step 1: Factor left side of equation.
(x+2)(x+3)=0
Step 2: Set factors equal to 0.
x+2=0 or x+3=0
x=−2 or x=−3
just a rough estimate!

For this case what we can do is the following rule of three:
152 -----> 2
x --------> 20
We clear the value of x:
x = (20/2) * (152)
x = 1520 tons
Answer:
in order to locate 20 ounces of diamonds the company needs:
x = 1520 tons of rock
Answer:
(-2, -4), (-1, -1), (0, 0), (1, -1), (2, -4)
Step-by-step explanation:
You plug in x values to get the y values are dot-in the points!
y = -x^2
You plug in -2 and get -(2)^2 = -(4) = -4
Same thing with all other values.
