Answer:
B. x = 2.77
Step-by-step explanation:
3^x = 21
You first look for a base for 21 that is 3 to the power of something.
21 = 3^2.77
So 3^x = 2^2.77
They have the same base so
x= 2.77
Answer:
220.5
Step-by-step explanation:
First, we can figure out the half circle. The area for that is pi times r squared divided by 2. So the area is 8 squared times pi divided by 2. So 64 divided by 2 is 32. 32 times pi is 100.530964915. We can round that to 100.5 and now the rectangle is 8 times 15. Which is 120. So 120 plus 100.5 is 220.5! I hope this helps! Please mark me Brainliest!!!
