Answer:
she need 2 13/24 yards of wire
Step-by-step explanation:
4 1/3 and 6 7/8
times the 4 1/3 by 8 for a common denominator of 24.
which gives you 4 8/24
times the 6 7/8 by 3 for denominator of 24.
so 6 21/24 subtract the 21 and 8 for 13, common denominator and then 6 minus 4.
2 13/24 yards
She jogged 3.9 miles. Just divide the 7.8 by 2.
C=2πr
a=πr²
common thing is r
hmm, solve for r in circumfernce
c=2π
=r
sub that for r in other
a=πr²
a=π
a=
so
c=8π
a=
a=
a=16π square inches
