Answer:

V ≈ 198 m³

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here diameter = 6, then radius r = 3 and h = 7 , then

V = 3.14 × 3² × 7 = 3.14 × 63 ≈ 198 m³ ( to the nearest whole number )

Question 6 of 15

umka2103 [35]

Answer:

$LE=5\ units$

Step-by-step explanation:

we know that

In a rectangle, the two diagonals are congruent and each diagonal bisects the other

$LN=2KE$ ----> equation A

$KE=LE$ -----> equation B

step 1

Find the value of x

solve equation A

$LN=2KE$

substitute the given values

$(2x+2)=2(3x-7)$

solve for x

$2x+2=6x-14\\6x-2x=2+14\\4x=16\\x=4$

step 2

Find the value of KE

$KE=3x-7$

substitute the value of x

$KE=3(4)-7=5\ units$

Remember that

$KE=LE$ -----> by each diagonal bisects the other

therefore

$LE=5\ units$

Answer:

$\bold{x=-4\pm\sqrt{46}}$

Step-by-step explanation:

$(a+b)^2=a^2+2ab+b^2\\\\\\x^2+8x-30=0\\\\\underbrace{x^2+2\cdot x\cdot 4+4^2}-4^2-30=0\\\\{}\qquad(x+4)^2\,-\,16-30=0\\\\{}\qquad\ \ (x+4)^2=46\\\\ {}\qquad\ \ x+4=\pm\sqrt{46}\\\\ {}\qquad\ \ x=-4\pm\sqrt{46}$
