The diameter of a tennis ball is 2 cm and the diameter of the softball is 1 cm. About how many times as

zmey [24]

Step-by-step explanation:

It is given that,

The diameter of a tennis ball is 2 cm and the diameter of the softball is 1 cm. So, radius of tennis ball is 1 cm and radius of softball is 0.5 cm.

Both balls are in the shape of sphere. Half of the balls will becomes hemisphere. The surface area of hemisphere is given by :

$A=2\pi r^2$

Taking ratio of both balls, i.e.

$\dfrac{A_1}{A_2}=\dfrac{r_1^2}{r_2^2}$

$\dfrac{A_t}{A_s}=\dfrac{r_t^2}{r_s^2}\\\\\dfrac{A_t}{A_s}=\dfrac{1^2}{(0.5)^2}\\\\\dfrac{A_t}{A_s}=4$

So, the surface area of a half of the tennis ball is 4 times of he surface area of a half of the softball.

X=3y+10 x=-8y-12<br><br> can u guys help me find the steps to solve this equations

Natalija [7]

Answer:

x=4, y=-2

Step-by-step explanation:

$x = 3y + 10 \\ x = - 8y -12\\ now \\ 3y + 10 = - 8y - 12 \\ 3y + 8y = - 12 - 10 \\ 11y = - 22 \\ y = \frac{ - 22}{11} \\ y = - 2 \\ again \: putting \: the \: value \:of \: y \\ x = 3y + 10 \\ x = 3( - 2) + 10 \\ x = - 6 + 10 \\ x = 4$
