Item 9 a softball has a volume of 1256π1256π cubic inches. find the radius of the softball.

1 answer:

5 0

$\boxed{\boxed{\text{Volume = } \dfrac{4}{3} \pi r^3}}$

Given that volume = 1256π, find radius:

$1256 \pi = \dfrac{4}{3} \pi r^3$

$r^3 = 1256 \pi \div\dfrac{4}{3} \pi$

$r^3 = 942$

$r= \sqrt[3]{942}$

$r = 9.8 \text{ inches (nearest hundredth)}$

Answer: The radius is 9.8 inches.

SpyIntel [72]

Answer:

Point slope form

y - 9 = 4(x-1)

Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is 4 x - y +5=0

Step-by-step explanation:

Step(i):-

Given that the points are (1,9) and (-1,1)

slope of the line

$m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }$

m = $\frac{1-9}{-1-1}$

m = 4

step(ii):-

Equation of the straight line passing through the point (1,9) and slope 'm' = 4

y-y₁ = m( x-x₁)

y - 9 = 4(x-1)

y -9 = 4x-4

4 x - y -4+9 =0

4 x - y +5=0

Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is 4 x - y +5=0

I don't what form of measurement to use (like grams, cusp, etc.) but I'm pretty sure it'd be cups

I think it's 5/96 or .05208333

So, 5/8 is .625. Dividing that up in throwing it into 12 cupcakes.
