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

Solve the following quadratic equation.
Nonamiya [84]

Given:

Consider the given equation is

(x-18)^2=1

To find:

The values of x.

Solution:

We have,

(x-18)^2=1

Taking square root on both sides, we get

x-18=\pm\sqrt{1}

x-18=\pm 1

Adding 18 on both sides, we get

x-18+18=\pm 1+18

x=\pm 1+18

Now,

x=1+18 and x=-1+18

x=19 and x=17

Therefore, the correct option is A.
