Answer:

242.76m^2

Step-by-step explanation:

Given data

Height=18m

Volume=4,374m^3

We know that the expression for the volume of a cylinder is

V=πr^2h

substitute

4374=3.142*r^2*18

4374=56.556*r^2

4374/56.556=r^2

77.339=r^2

r=√77.339

r= 8.79m

But the area of a circle is expressed as

A= πr^2

A=3.142*8.79^2

A=3.142*77.2641

A=242.76m^2

Hence the area of the base is 242.76m^2

What is the arc length if the radius is 12 cm?*
ladessa [460]

Answer:

 4π cm

Step-by-step explanation:

The length of an arc of a circle with radius r and central angle θ is given by ...

  s = rθ

where θ is in radians.

Here, your arc measures 60° = π/3 radians, so the arc length is ...

  s = (12 cm)(π/3) = 4π cm

Find the equation of the straight line passing through the point (3,5) which is perpendicular to the line y=3x+2
Levart [38]

Answer:

the desired equation is y = (-1/3)x + 6

Step-by-step explanation:

Let the given line be A:  y=3x+2

The slope of line A is m = 3.

The slope of any line B which is perpendicular to line A is the negative reciprocal of the slope of A:  m = -(1/3).

The particular perpendicular line that passes through (3, 5) is then

5 = (-1/3)(3) + b, which simplifies to 5 = -1 + b, or b = 6.

Thus, the desired equation is y = (-1/3)x + 6

What is three tenths times two and five sixths?
Virty [35]
To multiply fraction do top x top and bottom x bottom 
so convert 2 \frac{5}{6} into \frac{17}{6}
then do \frac{3}{10} * \frac{17}{6} =  \frac{3*17}{10*6} =  \frac{51}{60} =  \frac{17}{20}
