Answer:

157 cm³

Step-by-step explanation:

Given

height (h) = 6 cm

radius (r) = 5 cm

π = 3 . 14

Now

Volume of cone

= 1/3hπr²

= 1/3 * 6 * 3.14 * 5²

= 2 * 3.14 * 25

= 157 cm³

Hope it will help :)

which inequality is equivalent to 5x+2(3x+1)<3? a. 10x+2<3 b. 11x+2<3 c. 10x+1<3 d. 11x+1<3
hram777 [196]

5x + 2(3x + 1) < 3       Distribute 2 into (3x + 1)

5x + (2)3x + (2)1 < 3

5x + 6x + 2 < 3         Combine like terms(terms that have the same variable and power/exponent)

11x + 2 < 3       Your answer is B

Given:
oksian1 [2.3K]

Answer:

9 units

Step-by-step explanation:

By the midsegment theorem,

AB=\dfrac{KN+LM}{2}

Since the ratio LM:KN=1:5, then LM=x,\ KN=5x and

18=\dfrac{x+5x}{2}\\ \\18=\dfrac{6x}{2}\\ \\18=3x\\ \\x=6\\ \\LM=6\ units\\ \\KN=30\ units

Draw two heights LE and MF. Quadrilateral ELMF is a rectangle, then EF = LM = 6 units.

Trapezoid KLMN is isosceles trapezoid (KL = MN), then KE = FN and

KE=FN=\dfrac{KN-EF}{2}=\dfrac{30-6}{2}=12\ units

Consider right triangle KLE. By the Pythagorean theorem,

KL^2=LE^2+KE^2\\ \\15^2=LE^2+12^2\\ \\LE^2=15^2-12^2\\ \\LE^2=225-144=81\\ \\LE=9\ units
