Answer:
Yeah its 7 because when you add 3+2=5, and x is 2, its 7
458
Step-by-step explanation:
B.
1570
the formula for surface area of a cylinder is:
A= 2πrh + 2πr²
π aka pi = 3.14
r = 10
h = 15
so now plug in the numbers
A = 2(3.14)(10)(15) + 2(3.14)(10²)
A = 942 + 2(3.14)(100)
A = 942 + 628
A = 1570
