<h2>6.28</h2>
Step-by-step explanation:
<h2>Hi there</h2><h3>to understand this </h3><h3>you need to know about</h3>
- algebra
- circle
- area of semi-circle=½×πr²
it says to figure out the area of <u>semi-circle </u>not full circle
so
using the formula of area of semi-circle
<h3>=½πr²</h3>
=½×3.14 × 2²
=2×3.14
=6.28
First you make -1 3/5 into an improper fraction, -8/5
Since you're dividing a fraction by another fraction you'd change it to -8/5 × -3/2
(Don't forget to flip -2/3 to -3/2)
when you multiply it it'd be 24/10
(It is a positive number because when you multiply two negative numbers it becomes positive)
24/10 as a mixed fraction is 2 1/5
