Answer:

-20

Step-by-step explanation:

Use the distributive property to get $2xy-14$ (you multiply both xy and -7 by 2.) Now plug in the x and y values to get: $2(-1)(3)-14$ . This gets you $-6-14$ which is $-20$ .

Skee ball is a game played by rolling a wooden sphere up a ramp into a series of rings. The wooden ball has a surface area of ab

SVEN [57.7K]

Answer:

Radius of the ball is approximately 6.5 cm to the nearest tenth

Explanation:

The ball has the shape of a sphere

Surface area of a sphere can be calculated using the following rule:

Surface area of sphere = 4πr² square units

In the given problem, we have:

Surface area of the ball = 531 cm²

Substitute with the area in the above equation and solve for the radius as follows:

$531 = 4\pi r^2\\ r^2=\frac{531}{4\pi } = 42.255 \\ \\ r=\sqrt{42.255}=6.5004 cm$ which is approximately 6.5 cm to the nearest tenth

Hope this helps :)
