the radius of a standard baseball is about 3 in. about how many square in of horsehide required to cover 100 balls, to the neare

ipn [44]

Answer:

Step-by-step explanation:The surface area of a sphere (the shape of a baseball) is given by the formula, SA = 4 (pi) r^2. Given the circumference of the circle, you can solve for the radius.

The formula for circumference is C = 2 x pi x r.

So input 9 for C and solve. 9 = 2 x pi x r.

You will get that r is equal to about 1.43 in.

Now put that r value into the surface area equation: SA = 4 (pi) 1.43^2

You will get a surface area equal to about 25.7 in^2.

Now multiply that number by the number of baseballs you need to cover, 100.

I'll let you do that step by yourself since it's simple algebra and you're smart enough to figure it out ;)

A cylindrical can contains an unknown number of golf balls. The can has a height of 10 inches and a volume of 15.625 Pi inches c

AlladinOne [14]

20 golf balls can fit in the can.

<u>Step-by-step explanation:</u>

Given:

Height (h) = 10 Inches

Volume of 15.625 Pi inches cube.

To Find:

How many balls can be filled in that can.

Solution:

Diameter of the golf ball [as per standard value] = 1.68 in

Radius of the golf ball = $\frac{1.68}{2} = 0.84 in$

Volume of the golf ball = $\frac{4\pi r^3}{3}$

= $\frac{4\pi (0.84)^3}{3}$

= $2.5 (or) 0.79 \pi inches$

Volume of the can = $15.625\pi in^3$

Now we have to divide the volume of the can by the volume of the golf ball, we will get = $\frac{15.625 \pi }{0.79\pi } = 19.7$ balls

Thus we can conclude that approximately 20 balls can be filled in that can.
