<span> A) Diameter = 18"
Circumference = pi x Diameter = pi x 18 = 56.52"
Area = pi x radius^2 = pi x 81 = 254.34 sq. inches
B) Radius = 5 cm
Circumference = pi x Diameter = 10pi cm
Area = pi x radius^2 = 25pi square cm
C) Area = 64pi square cm
Radius = 8 cm
Diameter = 16 cm
Circumference = pi x Diameter = 16pi cm
OR (in case you wanted it exactly as you wrote it)
Area = 64 square cm
Radius = 4.51 cm
Diameter = 9.03 cm
Circumference = pi x Diameter = 28.35 cm
D) Diagonal = Diameter = sq root of (a^2 + b^2) = sq root (81+144) = 15 cm
Circumference = pi x Diameter = 47.10 cm
Area = pi x radius^2 = 23.55 square cm </span>

Answer:
13013
Step-by-step explanation:
Express each number in terms of the product of prime numbers.
91 = 7 × 13
143 = 11 × 13
169 = 13 × 13
Now consider the maximum number of times each factor occurs for each number.
The factor 7 occurs once
The factor 11 occurs once
The factor 13 is repeated twice ( maximum number of times for 1 number )
Thus LCM = 7 × 11 × 13 × 13 = 13013
65÷52=1.25
To change it to a percentage, multiply it by a 100
1.25×100%=125%
125% is the answer.
The answer to this is -4 and +13.
When you've got a negative number, this means that only one can be a negative number, and it is usually the smaller one.
-4*13= -52
-4+13= 9
Hope this helps :)
Answer:
- 36.00%
- 99.9976%
Step-by-step explanation:
Two mutually exclusive events that cover all possible events have a combined probability of 1.
1. If there is no middle ground—you either pass math or you don't—then the probability of not passing math this semester is 100% - 64% = 36%.
__
2. If there is no middle ground—you either win the lottery or you don't—then the probability of not winning the lottery is 100% - 0.0024% = 99.9976%.
