Answer:
A 1759 sq. units
Step-by-step explanation:
to find the surface area of a closed cylinder the formula is
2πr² + πdh
r = radius = 10
d = diameter = 10 + 10 = 20
2 x 3.14 x 10² + 3.14 x 20 x 18
628.3 + 1130.94 = 1759.24
ans = 1759
I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
Answer:
21
Step-by-step explanation:
Because h(3) times h(7) is equal to 21.
Hope it helps!
