Answer:
9
Step-by-step explanation:
Angles should be equal
Area of circle is πr^2
<u>Here</u>,
• π = 3.14
• d = 10
• so, r = d/2 = 10/2 = 5
<u>substituting the values in the formula,</u>
Area = 3.14 x 5 x 5
Area = 3.14 x 25
Area = 78.5 m^2
Hence, option (c) is correct.
Answer:
I can't see all of 3 but I can help with 5!!!
-2>-5
-1<4
-3>-10
-5<1
Step-by-step explanation:
for the negative ones, if they are both negative, the larger number is smaller than the other number. -5 is smaller than -2. for the other ones, positive numbers are larger than negative numbers.
Answer:
0.98
Step-by-step explanation:
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.13 + 0.85 - 0
P(A or B) = 0.98
Note that P(A and B) is 0. This is because we are told A and B are mutually exclusive events. This means both events cannot happen simultaneously. An example would be flipping a coin to have it land on heads and tails at the same time.
