So find the diameter which is the radius times 2
So 3x2= 6
6x 3.14(Pi)
=18.84 which a full circle and now divide by two
9.42 is the area of semi circle
The answer is 54 hope this helps
Answer:
my answer is B
Step-by-step explanation:
4+5+-6
4+5-6
(4+5)=9
9-6=3
Answer:
x = 7 and y = 17
Step-by-step explanation:
16x + 9x + 5 = 180 cuz they are supplementary
25x = 175
x = 7
We also know that 16x + 4y = 180
so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17
hope this makes sense
