Answer:
45
Step-by-step explanation:
year 1 : 18 in
every year after that he grows 3 in so 3 in so 3x9=27
then 27+18=45
9514 1404 393
Answer:
a. d = C/π
b. d = 8/π inches ≈ 2.546 inches
c. r = 61/(2π) inches ≈ 9.708 inches
Step-by-step explanation:
a. The formula for circumference is ...
C = πd
Dividing by π gives ...
d = C/π
__
b. For a circumference of 8 inches, the diameter is ...
d = (8 in)/π = (8/π) in ≈ 2.546 in
__
c. The radius is 1/2 the diameter. So, the radius of a circle is ...
r = d/2 = (C/π)/2 = C/(2π)
For a circumference of 61 inches, the radius is ...
r = (61 in)/(2π) = 61/(2π) in ≈ 9.708 in
The simplest way to find this number is to add your two known values (7 and 6) which should be 13. Now you should subtract it from 18. (18-13). That should equal to 5, which is your answer.
The answer would be 1/8 because when 1/8 is divide into the endpoints of AB you will recieve 1/8 of the endpoint numbers. Like 1/8 of 4 would be written as 1/8 times 4/1 since its a fraction multiply 1 times 4 and 8 times 1 to get 4/8. 4 goes into 4 one time and into 8 2 times giving you 1/2. Hope this helped.

Area =l×w
15.4=7×w
15.4/7=7/7w
2.2=w
Therefore the length of the height or width is 2.2ft
