Which expression correctly shows how to rewrite log11^5 using a log base of 8? log11^8/log5^8
log8^11/log8^5
log5^8/log11^8
log8^5/log8^11

Can someone check if i did this correct. it’s number 4 if you’re wondering.

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

Me. i can't figure out this question. give an explanation too. .
