Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
Answer:
it is 50.27
Step-by-step explanation:
the formula for finding the area it
A= pi r^2
pi=3.14
so that being said you want to:
you want to divide the diameter by 2 to get 4,then you want to do 4^2 to get 16. then multiply 16 by 3.14 to get 50.265 then you want to round up to 50.27
Maria has 19 hats.
b=beth
m=maria
Equations: 2b+5=m
b+m=26
plug in 2b+5 for m in equation 2: b+2b+5=26
add like terms: 3b+5=26
subtract 5 from both sides: 3b=21
Divide 3 from both sides: b=7
now plug in 7 for b: 7+m=26
subtract 7 from both sides: m=19
m=Maria
therefore Maria has 19 hats
