Answer:
a = 1/2
Step-by-step explanation:
The given equation is :
2y=ax-7 ...(1)
The point (2,-3) lies on the graph of this equation.
We need to find the value of a.
Put x = 2 and y = -3 in equation (1)
2(-3) = a(2) -7
-6 = 2a-7
-6+7 = 2a
2a = 1
a = 1/2
Hence, the value of a is 1/2.
R(2)=333*r(1)
C(1)=2πr(1)
C(2)=2πr(2)=2π*333r(1)
C(2)/C(1)=2π*333r(1)/2πr(1)=333
