a cone has a volume of 1,570in3. If the height of the cone is 15 inches. Calculate the radius of the cone?

spin [16.1K]

Answer:

approximately 10

Step-by-step explanation:

Volume = 1/3h times $\pi$ times radius square

1570 = 1/3 x 15 x 22/7 x $r^{2}$

1570 = 5 times $\frac{22}{7}$ times $r^{2}$

1570 = 15.71 $r^{2}$

$\frac{1570}{15.71}$ = $\frac{15.71 r^{2}}{15.71}$

99.9 = r^2

$\sqrt{99.9}$ = r

≅10

60% = 0.6 = 3/5
25.5% = 0.255 = 51/200
90% = 0.9 = 9/10
33 1/3 = 0.3333 =
62.5% = 0.625 = 5/8
7.5% = 0.07 = 7/100

So here, ABCD is being inscribed in a circle, so ABCD is a cyclic quadrilateral (as inscribed in a circle) also, there exists a property of cyclic quadrilateral, i.e, the sum of opposite angles of a cyclic quadrilateral is 180°, so we can just write the following equation using this :

${:\implies \quad \sf y^{\circ}+83^{\circ}=180^{\circ}}$

${:\implies \quad \sf y^{\circ}=180^{\circ}-83^{\circ}}$

${:\implies \quad \sf y^{\circ}=97^{\circ}}$

${:\implies \quad \boxed{\bf{y=97}}}$
