Answer:
.
Step-by-step explanation:
She has a total of long ribbon. If she cuts into two pieces and one of the pieces is . Then to find the lenght of the other piece we substract:
6 1/4
Total length of the ribbon= 15 3/4 m= 63/4 m
One piece= 9 1/2 m= 19/2 m
Other piece length =X
X= 63/4-19/2
=63/4-38/4
=25/4
=6 1/4
$243
81 x 3= 243 I'm pretty sure.
12.6 m^2
area of sector = 90/360 × 3.14 × 4^2
= 12.56
to the nearest tenth = 12.6 m^2
[ ISN} and {TSW} so the answer is D
