The height of a cylinder is 10 and the area of a base is 36 pi square units. What
ollegr [7]

Answer:

1130.97336 units^3

Step-by-step explanation:

The volume of a cylinder can be found using:

v=\pi r^2h

We have the area of the base, but not the radius

a=\pi r^2

We know the area is 36\pi, so we can substitute that in for a

36\pi =\pi r^2

We want to find r, so we need to isolate it

Divide both sides by pi

36=r^2

Take the square root of both sides

6=r

Now we know the radius, and can substitute it into the volume formula, and we can substitute the height (10) in

v=\pi r^2h

v=\pi 6^210

Solve the exponent

v=\pi 36(10)

v=\pi 360

v=1130.97336

The volume is 1130.97336 units^3

Please explain step by step
Alja [10]

Let's find the value of x

Since the sum of internal angles of a triangle is 180°

therefore,

\hookrightarrow \: (2x - 2) \degree + (x + 5) \degree + 90 \degree = 180 \degree

\hookrightarrow \: 2x - 2 \degree + x + 5\degree  = 180\degree - 90\degree

\hookrightarrow \: 3x + 3\degree = 90\degree

\hookrightarrow \: 3(x + 1) = 3(30)

\hookrightarrow \: x + 1\degree = 30\degree

\hookrightarrow \: x = 29\degree

ABCD is a parallelogram. If ad = 2x + 10 and CD = 4x - 20, for what value of x will abcd be a rhombus
dimaraw [331]

Answer:

15

Step-by-step explanation:

All sides of a rhombus are equal, so

2x+10=4x-20 \\ \\ 10=2x-20 \\ \\ 2x=30 \\ \\ x=15

The angle of a quadrilateral are A.P and the common difference is 10°. find the angles.
xxMikexx [17]

Step-by-step explanation:

So the Ap will be x,x+10,x+20,x+30

Sum of the angles of a quadrilateral is 360

x+x+10+x+20+x+30=360

4x+60=360

4x=300

x=75

So the angles are 75,85,95,105
