15/60<span> = x/100.</span>
cross multiply: 60x = 1500.
<span>now, divide both sides by 60 to isolate the variable x.</span>
Answer:
169π
Step-by-step explanation:
circle eq: (x-a)²+(y-b)²=r², where (a,b) is center and r is radius
r²=169
r = ±13
since a radius length must be positive, r = +13, not -13
A of circle: πr²
r = 13
169π
given that the circle eq has r², you could've noticed that you can take the constant in the circle eq and multiply that by π to get the same answer
The quotient is the answer to a division problem. And the factors are the numbers u are multiplying.
Tan(theta)=opposite/adjacent
Tan(31)=x/10
(Tan(31))10=x
X=6.0086
