Extract by Mask with two tiff images

[KimberlyHamm]

Hello,

I need to cut out a circle with a point and a 1000m radius. I downloaded the NAIP imagery from Earth Explorer but I had to download two images as no one single image covered the entire area I needed. It was cut off in all the available images. I was able to add two tiffs that I downloaded to ArcMap Pro. However when I try to use the Extract by Mask tool to cut out my circle, I must choose only one tiff instead of the combined image so I'm unable to move forward and extract bands, etc. I've attached a screenshot for clarification. How can I combine these images to make them one so that I can cut out my circle and it behave as one image from here on out?

Thanks in advance!

merge then extract?

Yes, that's exactly what I need to do but I don't understand how to do it. Why do they show how to write code for it? Where would I write that? Shouldn't there just be a tool that I can use? Sorry! New to all of this

It won't let me merge two.

I don't think they are multidimensional... multiband, yes
