Answer:
135
Step-by-step explanation:
3b + B = 180
4b = 180. ÷4
b = 45
a = 135
A. 12
12 isn’t a polynomial because the definition of a polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). So your answer will be A
We have been given volume of the cylinder which is 536.94 cubic inches. Now question says to find the radius of the cylinder.
Then we need to use formula of volume of cylinder which is given by :

We see that there are three unknown values in the formula: {volume, radius-r, height-h}
So to find any one of them we must know other two values.
Volume is given but height is missing. So just for explanation i'm going to use height of the cylinder h= 19 inches
Now plug the value of volume and height in above formula





take square root of both sides
3=r
Hence radius of the cylinder is 3 inches.

Answer:
A=195.97 cm^2
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We are given the diameter. We need to find the radius
d= 2r
15.8 = 2r
Divide by 2
7.9 =r
Now we can find the area
A = pi * (7.9)^2
A = pi *62.41
Let pi = 3.14
A = (3.14) * 62.41
= 195.9674 cm^2
We round to the nearest hundredths
A=195.97 cm^2
