Answer:
A = 64 pi inches ^2
Step-by-step explanation:
Circumference is equal to
C =2*pi*r where r is the radius
16 pi = 2 * pi *r
Divide each side by 2 pi
16pi/2pi = 2pir/2pi
8 = r
The radius is 8
To find the area, we use
A = pi r^2
=pi (8)^2
= 64 pi
For a right triangle, the Pythagorean theorem can be used to calculate the sides of the triangle. This theorem is expressed as: c^2 = a^2 + b^2. From th problem, we are given c which is the hypotenuse and the other leg which we will assign as the leg a. Calculation is as follows:
<span>c^2 = a^2 + b^2
(155cm)^2 = (124cm)^2 + b^2
b= 93 cm</span>
The sequence an=an−1+2 is an arithmetic sequence
The first three terms in the sequence are (a) 8, 10, 12
<h3>How to determine the first three terms?</h3>
The sequence is given as:
an=an−1+2
Where:
a1 =8
Start by calculating a2 using:
a2=a1+2
This gives
a2=8+2 = 10
Calculate a3 using:
a3=a2+2
This gives
a3=10+2 = 12
So, we have:
a1 = 8, a2 = 10 and a3 = 12
Hence, the first three terms in the sequence are (a) 8, 10, 12
