Answer:
1017.36 mm²
Step-by-step explanation:
d = 2r => r = d/2 = 36mm/2 = 18 mm
A = π·r²
= 3.14×(18mm)²
= 3.14×324mm²
= 1017.36 mm²
Answer:
1/3
Step-by-step explanation:
-2-4 = -6
-7-11 = -18
Each horse and person has 1 head
we know that people+horses=74
p+h=74
1 person has 2 legs
1 house has 4 legs
p=number of people
h=number of hourses
number of legs=196
4 times h=number of legs if h hourses
2p=number of legs if p people so
196=2p+4h
divide by 2
98=p+2h
multiply first equation by -1
-p-h=-74
add to current equation
p-p+2h-h=98-74
0p+h=24
there were 24 hourses
subsitute
24+p=74
ssubtract 24
50=p
there were 524 horses and 50 people
the answer is B
The new coordinates for B would be (1,4)
