Answer:
37.699 cm³
Step-by-step explanation:
Sa of cone:
pi×r×l + pi×r²
(3pi × l) + (pi × 3²) = 24pi
3l + 9 = 24
3l = 15
l = 5 (slant height)
Height: h
h² + r² = l²
h² + 3² = 5²
h² = 16
h = 4 cm
Volume = ⅓ × pi × r² × h
= ⅓ × pi × 3² × 4
= 12pi cm³
= 37.69911184 cm³
Answer:
Irrational Number: A number that cannot be written as a fraction
a
b
(where b ≠ 0), a repeating decimal, or a terminating decimal.
Rational Number: A number that can be written as a fraction
a
b
(where b ≠ 0), a repeating decimal, or a terminating decimal.
Repeating Decimal: A decimal where, when dividing, a digit or group of digits repeats without end in the quotient; there is a pattern in the digits that repeat without end.
Terminating Decimal: A decimal that, when dividing, ends with a remainder of zero.
Perfect cube: A number that is made by cubing a number: a3 = a • a • a.
Perfect square: A number that is made by squaring a number: a2 = a • a.
Cube Root:
if a3 = b, then a = 3√b
For principal square root this was the best I could do: The principle of square roots requires that the square root of the side with the unknown (x) only includes x without any exponent (other than 1). The simplest form that fits this criterion is: but x can also be an expression.
