. Correct option is D) 113.0 ft² .
<u>Step-by-step explanation:</u>
Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:
We know that area of circle =
, We have following parameters as

So , Area of circle is
⇒ 
⇒ 
⇒ 
⇒ 
On Rounding off
⇒ 
Therefore ,
. Correct option is D) 113.0 ft² .
Ratio given 1:2
Let's suppose the ratio as x : 2x
Adding the ratio = 3x


40 and 80 are in the ratio 1:2 of 120.
Hope it helps!!!
Answer:
maximum value of y = 3
Step-by-step explanation:
line Starts at -4 , 0 & turns at - 1 , 3
Slope = (3 - 0)/(-1 -(-4)) = 3/3 = 1
y = x + c
=> 0 = - 4 + c => c = 4
=> y = x + 4
line after turning crosses the y-axis at (0, 2) and the x-axis at (2, 0)
slope of this line : (0-2)/(2-0) = -1
y = - x + c
2 = 0 + c => c = 2
=> y = - x + 2
=> y = 2 - x

Answer:
10
Step-by-step explanation:
By Pythagoras' Theorem:
16 + r = √(24^2 + r^2)
(16 + r)^2 = 24^2 + r^2
256 + 32r + r^2 = 576 + r^2
32r = 320
r = 10
