19. a. r = 5m h = 6m find the surface area and volume of the cylinder. use 3.14.
Surface area = 2πrh + 2πr² = 2(3.14)(5)(6) + 2(3.14)(5)² = 188.4m²
Volume = πr²h = (3.14)(5)²(6) = 471m³
use 3.14 for pi show all work
Sure, here's the work:
Surface area = 2πrh + 2πr²
= 2(3.14)(5)(6) + 2(3.14)(5)²
= 94.2 + 157
= 251.2m²
Volume = πr²h
= (3.14)(5)²(6)
= 471m³
19. a. find the surface area and volume of the Rectangular prism use 3.14 for pi. l = 6 in h = 5 in w = 2 in
Surface Area = 2lw + 2lh + 2wh = 2(6)(2) + 2(6)(5) + 2(2)(5) = 104 in²
Volume = lwh = 6(5)(2) = 60 in³
show all work!
Sure, here's the detailed calculation:
Surface area = 2lw + 2lh + 2wh
= 2(6)(2) + 2(6)(5) + 2(2)(5)
= 24 + 60 + 20
= 104 in²
Volume = lwh
= 6(5)(2)
= 60 in³
