A=pie×radius squared is the area formula of a circle. The circumference formula or a circle is C=pie×diameter. 615.75=(3.14)(radius) squared. Divide both sides by the 3.14. What ever 615.75 divided by 3.14 is-is radius squared. The square root is your radius. The radius is half the diameter, so double what you have right now as the radius to get the diameter. Now since C=pie×diameter, your circumference is your pie×your diameter. Whatever your answer is-is your circumference.
Answer:
27+63=90
9(3+7) is the same as 27+ 63
Answer:
5
Step-by-step explanation:
Hi,
find the x- and y-intercepts:
10x + 4y = 20
finding x-intercept when y = 0
10x = 20
x = 2 Pt(2,0) the x intercept
finding y-intercept when x = 0
4y = 20
y = 5 Pt(0,5) the y intercept
