Y=m(3+2n) when m=4 and n=6

kobusy [5.1K]

Substitute 4 for m and 6 for n

Y= 4(3+2(6))
Y= 4(3+12)
Y=4(15)
Y=60

Please help me with this

Answer:

CD= 34

Step-by-step explanation:

As CD is the diameter the circle divides to half and point E is on the circle ∴∠CED =90° (angle of a semi circle)

as CD is the diameter it would be the lengthiest of all ∴ CD is hypotenuse

so $CD =\sqrt{16^{2} + \sqrt{30^{2} } } }$

= CD= $\sqrt{256+900}$

=CD= $\sqrt{1156}$

∴CD=34

Answer:

Hello,

Step-by-step explanation:

Area of the sphere:

$S=4*\pi *r^2$

Volume of the sphere:

$V=\dfrac{4*\pi *r^3}{3}$

$\dfrac{S}{3} =\dfrac{V}{7} \\\\\dfrac{4*\pi *r^2}{3} =\dfrac{4*\pi *r^3}{3*7} \\\\1=\dfrac{r}{7} \\\\\\r=7\\\\great \ circle: 2*\pi* r=14*\pi\\$

$Volume=\dfrac{4*\pi *7^3}{3} =\dfrac{1372*\pi }{3} \approx{1436,7550...(cm^3)}$
