Answer:
10.26 in²
Step-by-step explanation:
The area (A) of the sector is
A = area of circle × fraction of circle
= πr² × 
= π × 2.8² ×
≈ 10.26 in²
Answer:
5y - 5b
Step-by-step explanation:
Answer:
so to find slope for ordered pairs do y-y over x-x make sure the ordered pairs match up vertically
For simplifying radicals, remember the product rule of radicals: √ab = √a x √b . This radical is simplified as such:
√72 = √9 x √8 = 3 x √4 x √2 = 3 x 2 x √2 = 6√2
In short, the simplified radical of √72 is 6√2.
