Solve this equation for x 0.95 = log x
Lelechka [254]

Answer:

8.91

Step-by-step explanation:

Given:  0.95 = log x,

we can conclude that:

    0.95            log x

10             =  10

                                                          0.95

which in turn is equivalent to x = 10            whose value is  8.91

Circumference of a circle=diameter times pi

50.24=d(3.14)
d=16

radius is half of diameter so radius is 8

Area of a circle=pi(r^2)

(3.14)(8^2)=(3.14)(64)=200.96
