Radius
is half of the circle
diameter
is the whole thing inside the circle
since it is a radius, and it is a half of the full circle, we need to double out that number, and multiply by 2.
so here, you said it is 28
take 28, and multiply by 2, if you do every thing correctly, you should get:
56
so then answer would be 56 centimeters.
Hope that this helps you! =)
X/7-4=-2 u add two to both sides
x/7-2=0you add two to both sides again
x=14 u multiplied 7 and 2 and by x
Answer:
8,5 feet
Step-by-step explanation:
The equation of the form
x² + y² = (r)²
Is the equation of the circumference
We have for the pool:
x² + y² = 2500 ⇒ x² + y² = (50)²
And for the outside edge of the footpath
x² + y² = 3422,25 ⇒ x² + y² = (58,5)²
So we obtain the radius of each circumference
For the outside edge of the pool r₁ = 50 feet
For the outside edge of the footpath r₂ = 58,5 feet
Then the width of the footpath is 58,5 - 50 = 8,5 feet
Answer:
a. 99.99 * .15 = 15 dollars off (14.9985 dollars)
b. 175000 *.07 = $12,250
c. rent = $2500 = x
y = total budget
y = 2500/.12 = $20,833.33
d. d = .19 * r
