Answer:
1) 59.7 2) 7.1
Step-by-step explanation:
1)The diameter of a circle is 19 m. Find the circumference to the nearest tenth
The equation to find the circumference for a circle is C=2πR or C = πD. The diameter is equal to 2r so that is why the equation works either way. Now we will plug in the numbers. C =19π. This is approximately equal to 59.6902604182 which is approximately equal to 59.7
2)AND the diameter of a circle is 3ft. Find its area to the nearest tenth.
As stated before the diameter is equal to 2r. The area of a circle is calculated using the equation πr^2. First we need to find the radius which is 1/2D. 3/2 = r or 1.5 = r. Now we can plug all values in. A = π1.5^2 which equals to 2.25π which equals to 7.06858347058 which is approximately 7.1.

Answer:
y=8/13, 10/13=x
Step-by-step explanation:
-2y = x-2, so 2y = -x+2. y = -1/2x+1, and we plug this in -4x+3y to get
-4x-1.5x+3=x-2
-5.5x+3=x-2,
-6.5x=-5
13x=10
x=10/13.
for y we plug the x in to get -40/13=-5y
40/13=5y
y=8/13
Answer:
Inches: 12, 36, 60, 108
Feet: 1, 3, 5, 9
Step-by-step explanation:
Inches: 12, 36, 60, 108
Feet: 1, 3, 5, 9
3*12 = 36
60/12 = 5
108/12 = 9
