Answer:
See below ~
Step-by-step explanation:
<u>Circle 1</u>
- Circumference = 2πr = 2 x 3.14 x 2.5 = 5 x 3.14 = 15.7 m
- Area = πr² = 3.14 x (2.5)² = 3.14 x 6.25 = 19.625 m²
<u>Circle 2</u>
- Area = πr² = 3.14 x 1² = 3.14 mm²
- Circumference = 2πr = 2 x 3.14 x 1 = 6.28 mm
 
                                
             
                    
              
              
                
                
Answer:
circumference with diameter 5=15.7m
area with diameter 5=19.625m²

Answer:
27.8
Step-by-step explanation:
You need to do brackets first
3.6-1.8 = 1.8
Then substitute
4.5 x 8- (0.4 + 9.6- 1.8)
0.4+9.6-1.8=8.2
4.5 x 8 - 8.2 =27.8
