Help please, this is geometry btw

Acylinder has volume 45π and radius 3. what is it’s height?

Can someone show me step by step how to do this?

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
