The area for a circle with a diameter of 8 cm is 50.24 cm². The area of a circle with a radius of 3 cm is 28.26 cm². 50.24 - 28.26 = 21.98 cm. So the difference is 21.98 cm.
Answer:
x = 40
Step-by-step explanation:
The answer is x = 40. This is because the two angles that are x are 1. congruent and 2. supplementary with 100° (They all add up to 180°). I can show this with a simple equation.
1. 2x + 100 = 180
2. 2x = 80
3. x = 40

Step-by-step explanation:
Answer:
2 / 13
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of 4's = 4 ( 1 for each suit)
Number of 6's = 4 (1 for each suit)
Probability, P = required outcome / Total possible outcomes
P(a 4) = 4 / 52 = 1/ 13
P(a 6) = 4 /52 = 1/13
Probability of either a 4 or a 6
P(a 4) + P(a 6)
1/13 + 1/13
= 2 / 13

Answer:
D) 4pi(3.7)^3/3
Step-by-step explanation:
The formula for the volume of a sphere is ...

This is given in terms of the radius, which is half the diameter
r = d/2 = (7.4 cm)/2 = 3.7 cm
Using this value in the formula, we have ...
