Radius of a circle with a circumference of 28 (3.14)

the answer is 82.9

Step-by-step explanation:

You need to multiply

Pi is about 3.14. Then the equation for circumfrance is     2(3.14)(R). Then you can first simplify that more to get an approximation of the circumference formula, which is 6.28R. Then you set that equal to the value of the given circumfrance, which is 28(3.14), or 87.92. So:

6.28R = 87.92.

Divide it all by 6.28 to get:

R = 14.

Radius equals to 14.

'' For the functionf(x) = -6(1.02)^x
The y-intercept can be determined when x = 0f(0) = -6(1.02)^0f(0) = -6
For the function g(x)At x = 0, the value of g(0) = -3
Therefore, comparing the y-intercepts of the two functions, the answer is:B. The y-intercept of f(x) is equal to 2 times the y-intercept of g(x).''
