Surface area is 4piR^2
Volume is 4/3 piR^3
R is the radius (half the diameter). Just plug in the numbers
The measure of <u>angle b</u> is 112° and the measure of <u>angle c</u> is 68°
<h3>Calculating the measures of angles </h3>
From the question, we are to determine the measures of the missing angles
From the diagram,
b = 112° (<em>Vertically opposite angles</em>)
∴ b = 112°
Also,
112° + c = 180° (<em>Sum of angles on a straight line</em>)
c = 180°- 122°
∴ c = 68°
Hence, the measure of <u>angle b</u> is 112° and the measure of <u>angle c</u> is 68°

Answer:18
Step-by-step explanation:
18
If im not mistaken the answer is D 270
Answer: A) 46.5 cm
Step-by-step explanation:
Circumference = 2 π r or Circumference = π d
In this case, they give us the diameter = 14.8 cm. Therefore the radius = 14.8/2 = 7.4 cm.
π ≈ 3.14.
We can use either equation above, but because the diameter was given, we will use c = πd for simplicity.
C = π d
= (3.14)(14.8)
= 46.47 cm, which rounds to 46.5 cm
