The formula for the bowline of a sphere is V=4/3πr^3. solve for r

Tpy6a [65]

Answer:

$r=\sqrt[3]{\frac{3V}{4\pi}}$

Step-by-step explanation:

$v= \frac{4}{3} \pi r^3$

We need to isolate 'r'

To isolate 'r' , first multiply by 3 on both sides

$3v=4* \pi r^3$

divide by 4pi on both sides

$\frac{3V}{4\pi} = r^3$

Take cube root on both sides

$\sqrt[3]{\frac{3V}{4\pi}}= r$

Answer:

Step-by-step explanation:

Use the formula for the area of a triangle,

Area of a triangle = $\frac{1}{2}(\text{Base})(\text{Height})$

7). Area of the triangle = $\frac{1}{2}(20)(7.4)$

= 74 km²

8). Area of the triangle = $\frac{1}{2}(4)(15.4)$

= 30.8 cm²

9). Area of the triangle = $\frac{1}{2}(16)(7)$

= 56 m²

10). Area of the triangle = $\frac{1}{2}(11)(7.7)$

= 42.35 km²
