Question
rodikova [14]

Answer:

Volume = 11488.21

Area = 2461.76

Step-by-step explanation:

Given

Radius, r = 14\ in

Shape: Sphere

Solving (a): The Volume

This is calculated as:

Volume = \frac{4}{3}\pi r^3

Take \pi as 3.14 and substitute 14 for r

Volume = \frac{4}{3} * 3.14 * 14^3

Volume = \frac{4}{3} * 3.14 * 2744

Volume = \frac{4 * 3.14 * 2744}{3}

Volume = \frac{34464.64}{3}

Volume = 11488.21

Solving (b): The Surface Area

This is calculated as follows:

Area = 4\pi r^2

Take \pi as 3.14 and substitute 14 for r

Area = 4 * 3.14 * 14^2

Area = 4 * 3.14 * 196

Area = 2461.76

What is the value of the 35th term in the sequence -15, -11, -7, ...? 121 125 151 374
Andreas93 [3]

Answer:

121

Step-by-step explanation:

This is an arithmetic sequence.

First term  a = -15

Common difference [d] = second term - first term

                                  = -11 - [-15] = -11 + 15 = 4

nth term = a + (n-1) * d

35th term = -15 + (35 - 1) * 4

                = -15 + 34 * 4

                = - 15 + 136

                = 121
