Answer:

C. 8,624

Step-by-step explanation:

recall that the formula for circumference is

Circumference = 2πr ( = given as 85 meters)

hence,

85 = 2πr

r = 85/(2π)

given h = 15m

volume of cylinder

= πr²h

= π (85/2π)² 15 (using calculator and assuming π = 3.14)

= 8628.58

Comparing with the choices, the closest choice (within rounding error) is C. 8,624

Answer:

The value of x is 6

Step-by-step explanation:

Since it's a parallelogram both sides are the same so the bottom equation needs to equal 15 m, therefore 2*6+3=15.

(f-g)(x) with f(x)=x + 6, g(x) = x -6

(F-g)(x)= (x-6) + 6
= x-6+6
= x

azamat

The point-slope form:

$y-y_1=m(x-x_1)$

We have a slope m = 4 and the point (-3, -1). Substitute:

$y-(-1)=4(x-(-3))\\\\\boxed{y+1=4(x+3)}\to\boxed{b}$
