Area of semicircle is given by:

r is the radius, and we are given the diameter. Radius is half the diameter, so it's 2.5m. Let's plug that into the formula (using 3.14 as an estimation for pi):

So, the area of this semicircle is
9.81m².
Answer:
1394
Step-by-step explanation:
Set up equation to find the number:
Variable n = number
65/100 = 1105/n
Cross multiply:
65 × n = 100 × 1105
65n = 110,500
n = 1700
Check your work:
1700 × 65%
Convert percentage into decimal:
1700 × 0.65
1105
Correct!
Find 82% of 1700:
Variable x = 82% of 1700
82/100 = x/1700
82 × 1700 = 100 × x
139,400 = 100x
1394 = x
Check your work:
1700 × 82%
1700 × 0.82
1394
Correct!
Answer:
empty spaces in order from left to right are 16,12,42
Step-by-step explanation:
because your adding one to the 5 so you add one to the 15 then your × by 12 bc 3×12 is 36 and × by 12 on the top so 6×12 then last one ur adding 6 because 12+6 is 18 and what ever you do to the top or bottom you do the the bottom or top
Ok so obvi you can’t multiply 1/6 so u have to divide top on bottom out so 1 divided by 6 so your awnser would be 2.5
Y-y1=m(x-x1)
m=slope
y-(-2)= (2/3)(x-3)
y+2=2/3x - 2
