Determine The Surface Area Of Each Cylinder. Use 03c0= 3.1416.
Determine the surface area of each cylinder. Use π= 3.1416.
Answer: #10= 326.7264 cm^2, #11= 61.2612cm^2
Step-by-step explanation:
Formula for cylinder SA= 2πrh+2πr^2
10. r= 4cm, h=9cm
SA= 2(13.1416)(4)(9)+2(3.1416)(4)^2
SA= 226.1952 cm^2 +100.5312 cm^2
SA= 326.7264 cm^2
11. r= 1.5cm, h=5cm
SA= 2(13.1416)(1.5cm)(5cm)+2(3.1416)( 1.5)^2
SA= 47.124 cm^2 +14.1372 cm^2
SA= 61.2612 cm^2
