Answer: the area is 20 square centimeters.
Step-by-step explanation:
The area of an arc of angle x in a circle of radius r is:
A = (x/3.14)*3.14*r^2 = x*r^2
here we have x = (4/5)*3.14 and r = 5cm
Then the area is:
A = (4/5)*(5cm)^2 = 20cm^2
D because you know it can’t be a or b and the bigger number goes first
The answer is C.
Perpendicular lines have opposite reciprocal slopes. That means one is negative and the other is positive, and the fractions are flipped.
Answer:
Step-by-step explanation:
Let the be the first number, be the second number and be the product of the first and second number.
i.e
Now,
Hence,
Answer:
0.28
Step-by-step explanation:
Let p be the probability of pasta.
Total probability is = 1
Therefore,
0.3 + 0.42 + p = 1
0.72 + p = 1
p = 1 - 0.72
p = 0.28
The probability that it will be pasta is 0.28
