Answer:

64n = 4nr2

Step-by-step explanation:

So the formula for the surface area of a sphere is A=4πr^2

Now A= 64n

(im assuming n is supposed to be pi)

so 64n=4πr^2

thus the last one would be correct (also assuming its supposed to be r^2)

A wooden board has a volume of 0.225 cubic m and a mass of 146.25 kilograms.
Triss [41]

Answer:

650 kg/m³

Step-by-step explanation:

The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.

 density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³

 = 650 kg/m³

Hope this answer helps you :)

Have a great day

We have to find horizontal component of Mayosons velocity.

#a

\\ \tt\bull\leadsto V_x=vsin\theta

\\ \tt\bull\leadsto V_x=2.5sin36

\\ \tt\bull\leadsto V_x=2.5(0.58)

\\ \tt\bull\leadsto V_x=1.45m/s

#b

Here 2 vectors A=8 and B=2.5

\\ \tt\bull\leadsto \overrightarrow{R}

\\ \tt\bull\leadsto \sqrt{A^2+B^2+2ABcos\Theta}

\\ \tt\bull\leadsto \sqrt{8^2+2.5^2+2(8)(2.5)cos36}

\\ \tt\bull\leadsto \sqrt{64+6.25+40(0.8)}

\\ \tt\bull\leadsto \sqrt{70.25+32}

\\ \tt\bull\leadsto \sqrt{102.25}

\\ \tt\bull\leadsto 10.15m/s
