Answer: 88 inches
Step-by-step explanation:
We know that the formula to find the circumference of circle is given by :-
, where r is the radius of the circle.
Given : Diameter of circle = 28 inches
Also, diameter is twice of radius.
i.e. 2r=28
Therefore, the circumference of circle will be :-

Hence, the circumference of circle is 88 inches.
X^2+x+8 is the answer unless you need it factored
For Question 1:
angle CAB, angle ABC, angle BCA
Question 2: angle BCD
Answer:
See below
Step-by-step explanation:
To begin, it is volume, not area
1. 8 x 12 x 17 = 1632 in ^3
5. 9 x 9 x 13.5 = 1093.5 in^3
If you want to find SURFACE AREA:
1. 2(8 x 12) + 2(8 x 17) + 2(17 x 12) = 872 in^2
5. 2(9 x 9) + 4(9 x 17) = 774 in^2
