What is the diameter of a hemisphere with a volume of 8514 cm', to the nearest

Mandarinka [93]

Answer:

32.0 cm

Step-by-step explanation:

volume of a hemisphere = (2/3)πr3

r = cube root (Volume * 3/2 * 1/π )

r = cube root ( 8514 * 3/2 * 1/π)

r = 15.96

in the nearest tenth r = 16.0 cm

D= 2r

D= 2(16)

D= 32cm

Express the area of the rectangle in term of x

aalyn [17]

Answer:

Area = $12-\frac{4}{35}x$

Step-by-step explanation:

Length of the given rectangle 'l' = (15 - $\frac{1}{7}x$ )

Width of the given rectangle 'w' = $\frac{4}{5}$

Area of the rectangle = lw

= $\frac{4}{5}(15-\frac{1}{7}x)$

= $\frac{4\times 15}{5}-\frac{4}{5}\times \frac{1}{7}x$

= $12-\frac{4}{35}x$

Therefore, expression that defines the area of the given rectangle will be,

Area = $12-\frac{4}{35}x$
