Answer:
The circumference of the circle is 52π
Step-by-step explanation:
To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius
a = area = 676π
r = radius
a = π * r²
we clear r
r = √(a/π)
now we replace the known values
r = √(676π/π)
r = √(676)
r = 26
now we use the formula to calculate the circumference of a circle
c = π * 2r
c = π * 2 * 26
c = 52π
The circumference of the circle is 52π
Answer:
Ratio of sweaters to dresses = 8 : 5
Sum of ratios = 13
Let number of sweater + dresses = x
I think it’s 40
The width is 8
And the length is 5
8 x 5 is 40
So it means every 30 minutes he runs 6 miles
Monday : 2 + 10*0,25 = 2+2,5 = 4,5
Sunday : Monday - 0,3*Monday = 4,5 - 0,3*4,5 = 4,5 - 1,35 = 3,15
It's cheaper for 4.5 - 3.15 = 1,35
