Answer:
Step-by-step explanation:
slant height = l = 15 mm
radius = r = 7 mm
Surface area of cone = πr (l + r) square units
= 3.14 * 7 *(15 + 7)
= 3.14 * 7 * 22
= 483.56 square mm

Step-by-step explanation:
Answer:
Step-by-step explanation:
1) true
2)3/4x-6= 12 = true
3) 8= -2x + 4 = false
4) x+5 = -3 = false
5) -3= 5-2x = true
A, B and D are already rational numbers, 0.4 itself is a rational number, two rational numbers make a product of rational number.
So A, B, D are the correct choices.
Are you sure it asks for rational numbers, not irrational number?
