9 Find mZWVT T 35x-2 U 93 ° W V 7x + 5 mZWVT =

nikitadnepr [17]

Answer:

Step-by-step explanation:

$\frac{35x - 2 - 93}{2} = 7x + 5$

$\frac{35x - 95}{2 } = 7x + 5$

$17.5x - 47.5 = 7x + 5$

$17.5x = 7x + 52.5$

$10.5x = 52.5$

$x = 5$

Plug 5 in for 7x+5.

$7(5) + 5 = 40$

Solve.

Serhud [2]

Answer:

Step-by-step explanation:

12.9 + 10.2x = 35.1

10.2x = 35.1 - 12.9

10.2x = 22.2

x = 22.2/10.2

x= 222/102 = 111/51

$x= 2\dfrac{9}{51}$

The Volume of a sphare is 28/3 times the surface area calculate The surface area and the Volume of the sphere, correct to the ne

Aloiza [94]

Given:

Volume of a sphere is $\dfrac{28}{3}$ times the surface area.

To find:

The surface area and the volume of the sphere.

Solution:

Volume of a sphere:

$V=\dfrac{4}{3}\pi r^3$ ...(i)

Surface area of a sphere:

$A=4\pi r^2$ ...(ii)

Where, r is the radius of the sphere.

Volume of a sphere is $\dfrac{28}{3}$ times the surface area.

$V=\dfrac{28}{3}\times A$

$\dfrac{4}{3}\pi r^3=\dfrac{28}{3}\times 4\pi r^2$

Multiply both sides by 3.

$4\pi r^3=112\pi r^2$

$\dfrac{\pi r^3}{\pi r^2}=\dfrac{112}{4}$

$r=28$

Using (i), the volume of the sphere is:

$V=\dfrac{4}{3}\times \dfrac{22}{7}\times (28)^3$

$V\approx 91989$

Using (ii), the surface area of the sphere is:

$A=4\times \dfrac{22}{7}\times (28)^2$

$A=9856$

Therefore, the surface area of the sphere is 9856 sq. units and the volume of the sphere is 91989 cubic units.

How do you find the area of a circle with the circumference?

Naya [18.7K]

Circumference = 2*pi*radius

find the radius using this formula.

then use this formula => area of circle = pi*radius*radius

put the value of the radius that you get with the first formula to find the area

hope it helps you
