Find the volume of a cylinder with base diameter 140cm and height 10cm. (22/7)
jeyben [28]

Step-by-step explanation:

could not find the formula ?

the volume of a cylinder is ground area × height.

and the ground area is a circle.

so, all in all we get

pi×r²×h

with r being the radius (half of the diameter), and h being the height.

in our case we get

pi×(140/2)²×10 = pi×70²×10 = 49000×pi =

= 153,938.04... cm³

We’re told that QR and RS are equal, so this is an isosceles triangle.

Meaning the two base angles must also be equal

Using this information, we know that the third angle must be 180 - (22 + 22), since the angles in a triangle add up to 180

Find the midpoint of diagonal WY.. . Figure WXYZ is shown. W is at 0, 2. X is at 0, 6. Y is at 6, 6. Z is at 6, 2.. . (2, 4). .
Anestetic [448]

Answer:

(3,4)

Step-by-step explanation:

we know that

The formula to calculate the coordinates of the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have that

The coordinates of diagonal WY are

W(0,2), Y(6,6)

substitute in the formula to calculate the midpoint

M(\frac{0+6}{2},\frac{2+6}{2})

M(\frac{6}{2},\frac{8}{2})

M(3,4)
