Answer:
99.0 in²
Step-by-step explanation:
The area (A) of the sector of the circle is calculated as
A = area of circle × fraction of circle
= πr² ×
( where r is the radius )
Here r = 9, thus
A = π × 9² × 
= 81π ×
≈ 99.0 in²
Answer:
her profit is $25
Step-by-step explanation:
Given that
She spends $15 for purchasing fabric so that she make the baby blankets
And, she can make 4 blankets from one piece of fabric
Now she sold the blankets for 10 each
So we need to find out the profit
As we know that
Profit = Selling cost - purchasing cost
= (4 × $10) - $15
= 40 - $$5
= $25
hence, her profit is $25
The first 3 are correct but for the last one I’m not sure
