I WILL GIVE BRAINLIEST. PLZZZ HELP ME A colony of bacteria forms a circle with a diameter of 80 mm. What is the area of the
colony?
50.3 cm
20.100 mm
5030 cm
50 3 mm​

area = r² * π

40² *π

1600 * 3.142 = 5027.2 cm²

Explanation:

if the diameter is 80 then this is the asnwer , and the diameter divide it by 2 so u can find the radius

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
