Answer: Area= 459.73cm^2
Step-by-step explanation: Circumference of a circle is 2πr
76=2×3.14×r
r= 76÷(6×3.14)
r=12.10
Area of a circle= πr^2
Area= 3.14×(12.10)^2
Area= 456.73cm^2
Answer:
8*2^(n-1)
Step-by-step explanation:
This is a geometric sequence since we multiply from the previous term.
a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.
The first term is 8, so we have
a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)
Denise is the fastest runner. 40 divided by 6 is 6.666 repeating 30 divided by 5 is 6 and 20 divided by 4 is 5 therefore denise is fastest
Answer:
9/5 (-8) > = F > = 9/5 (157)
Step-by-step explanation:
A. -40>= 5/9F - 32
-40+32>= 5/9F
9/5(-8) >= F
B. 125 <= 5/9F - 32
125+32 <= 5/9F
9/5(157) <= F
9/5 (-8) >= F >= 9/5 (157)
