Answer:
surface area of sphere = 615.44mm²
volume of sphere = 523.33mm³
Step-by-step explanation:
S.A = 4πr²
4 × 3.14 × 7 × 7 = 615.44.
volume = 4πr³/3
4 × 3.14 ×5 × 5 × 5 ÷ 3 = 523.33
Answer:
84 degrees because both angles are equal.
Answer:
8
Step-by-step explanation:
radical form conversion uses the equation: 
Use the rule to convert 4^3/2 to a radical, where a = 4, x = 3, and n = 2
simplified, your answer is 8
hope this helps:)
<span>time for airplane = 11 am to 1 pm = 2 hr
distance travelled by plane = 2a ------- (speed of plane is a mph)
time for auto = 3 am to 1 pm = 10 hr
distance travelled by plane = 10(a – 200)
2a = 10(a – 200)
8a = 2000
a = 250 mph ----- plane
and 250 – 200 = 50 mph ----- auto </span>
Answer:
<h2>See below</h2>
Step-by-step explanation:
Theoretical probability is the actual chance of something happening based on raw numbers.
For example: The theoretical probability of tails on a coin flip is 1/2 or 50%. If you flipped a coin, you would expect 50% to be heads, 50% to be tails.
However, since this almost never happens, experimental probability is used to describe the actual results.
For example: If you flip the coin 50 times and 23 are tails, 27 are heads, then the experimental probability is 46% for tails and 54% for heads.
I'm always happy to help :)
