Vikentia [17]3 years ago

Given the equation 4(3b + 2)² = 64, dividing both sides of the equation by 4, we have (3b + 2)² = 16 and getting the square root of both sides, (3b + 2) = 4 and (3b + 2) = -4 We can solve for b for each equation and have 3b = 2 | 3b = -6 b = 2/3 | b = -2 Therefore, the values of b are 2/3 and -2 and from the choices, the answer is <span>A: b = 2/3 and b = -2.</span>

Find the volume of a right circular cone that has a height of 4.5 ft and a base with a diameter of 19 ft. Round your answer to t
guapka [62]

Answer:

Volume of the cone= 425.07feet^3

Step-by-step explanation:

Volume of a right circular cone:

                              \frac{1}{3} *\pi *r^2*h

For,     height(h)= 4.5 feet

Diameter= 19 feet

Radius(r)= 19/2= 9.5 feet

As, \pi =\frac{22}{7}=3.14

Volume of the cone :

                               =\frac{1}{3} *3.14*(9.5*9.5)*4.5\\\\=\frac{1}{3}*3.14* 90.25*4.5\\\\=\frac{1}{3} *3.14*406.125\\\\=\frac{1275.23}{3}\\\\ =425.07feet^3

The volume of the cone with given dimensions is 425.07feet^3
