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.
In triangle ABC, angle B is 90° and angle A is 45° => triangle ABC is Isosceles triangle. That means side AB = BC
Also, side AC² = AB² + BC² = 2BC²
(6√2)² = 2BC² => 36*2
BC = 6
In triangle BCD, angle D is 90° and angle B is 60° => triangle BCD is semi Equilateral triangle. That means side BD = ½BC = 6/2 = 3 which is the value of X.
Good luck
Answer:
The number of fishing boats in the bay = 64.
Step-by-step explanation:
The total number of sailboats = 24
Let us assume the number if fishing boats in the bay = m
⇒ Ratio of fishing boats to sailboats in a bay = m : 24.
Now, the ratio of fishing boats to sailboats in a bay is 8 : 3.
So, by the RATIO OF PROPORTION:
⇒ m = 64
Hence the number of fishing boats in the bay = 64.
Answer:
25
Step-by-step explanation:
