A cone with volume 246 ft cubic if the height is 15 find the radius
Liula [17]

Answer:

r = 3.95 ft

Step-by-step explanation:

Volume of cone = \frac{1}{3} \pi r^{2} h = 246 ft³

246 = \frac{1}{3} * \frac{22}{7} * r^2 * 15

r² = \frac{246*3*7}{22*15*5}

r = \sqrt{15.65}

r = 3.95 ft

How to find cp if loss and sp are given​
velikii [3]

Step-by-step explanation:

\tt{ \: H \: E \: Y \: \:  T \: H \: E \: R\: E \: } !

When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :

✰ \large{ \boxed{ \boxed{ \tt{CP = Loss + SP}}}}

\text{How \: did\: we \:get  \:the \: formula :  \: CP \:  = Loss \:  +  \: SP} \: ?

We simply derived the formula from Loss = CP - SP.

First , Swap the sides of the equation :

⟶ \text{CP - SP = Loss}

Move SP to right hand side and change it's sign :

⟶\text{CP = Loss + SP}

This is how , CP can be obtained when we are given loss and SP.

Hope I helped ! ♡

Have a wonderful day / night ! ツ
