I believe it would be D. If d=7 then the equation would be 2x7 which would equal 14
Is there any way you can add the graph on here?
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
Since there’s four of each card, there would be 12
12 out of 52 cards would be 3,4, or 5
