Step-by-step explanation:

V = πr2h

r - radius

h - height

π - pi

Small cyclinder

= π(3)2(10)

enter into a calucaltor and you get 282.74

Big cyclinder

= π(6)2(10)

enter into a calucaltor and you get 1130.97

Divide 1130 by 282 and you get about 4

If m angle B=m angle D=41, find m angle C so that quadrilateral ABCD is a parallelogram

Charra [1.4K]

ANSWER

139°

EXPLANATION

One of the interior angle properties of a parallelogram is that adjacent interior angles are supplementary.

This means that, the adjacent interior angles add up to 180°.

$m \angle \: B = m \angle \: D = 41$

Then

$m \angle \: C + m \angle \: D = 180 \degree$

$m \angle \: B + m \angle \:C= 180 \degree$

$\implies41 \degree + m \angle \:C= 180 \degree$

$\implies m\angle \:C= 180 \degree - 41 \degree = 139 \degree$
