So since 11/pi doesn't means 11 divided by pi but it means 11 pi
circumference=2pir
if circumerence=11pi
2pir=11pi
solve for r (radius)
divide both sides by pi
2r=11
divide by 2
r=5.5
area=pir^2
area=pi5.5^2
area=pi30.25
answer is area=30.25pi in^2
Answer:
The answer is A
Step-by-step explanation:
y=1.3(5) + 10 = 16.5 ---> True
y=1.3( 10) + 10 = 23 ----> True
y=1.3(15) + 10 = 29.5 ----> True
y=1.3(20) + 10 = 36 ----> True
Multiply the amount of paint started with by the amount used:
2/3 x 1/2 = (2 x 1) / (3 x 2) = 2/6 = 1/3
There is 1/3 liter left
Answer:
Step-by-step explanation:
a^2+b^2=c^2
5^2+b^2=16^2
25+b^2=256
b^2=231
b=
Answer:
l( longer side ) = 12cm
S (shorter side) =9cm
D's( distance between the shorter side). ( It is also the height. I hope you got the clue…)
Anyway,
Area=9X8=72cm^2
Distance of the longer sides is
Area/the length of the longer side
72/12=6cm…
Distance between the longer sides is 6cm
Hope this helps…
