The surface area of a sphere is given by

where r represents the radius.
As the radius is given as 60 meters we replace r with 60 in the formula above to get the surface area.
Find the cost for one ticket for the science center.
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153
The <u><em>Zoo</em></u> costs more than the Science Center.
To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs <u><em>$6 </em></u>more for 12 students.
So, you're answers are Zoo and $6
