Answer: 63 ft^2
Step-by-step explanation:
the formula for the area of a circle is A = π r ^2. the radius (r) is 1/2 of the diameter.
first, we'll plug in the radius of table #1 into the equation (A = π 4 ^2) and get an answer of 50.27 ft^2. then plug in radius of table #2 (A = π 6 ^2) and get 113.1 ft^2. now find the difference of the areas by subtracting (113.1 - 50.27) to get an answer of 62.83 ft^2. which will round up to 63 ft^2.
If the areas of two equilateral triangles are 27 yd² and 75 yd², then the ratio of these areas is 27/75 = 9/25
If the ratios of the areas are 9:25, then their similarity ratio and the ratio of their perimeters is √9:√35 = 3:5.
3 : 5; 3 : 5 <==ANSWER
Answer:
f(- 6) = 9
Step-by-step explanation:
to evaluate f(- 6), substitute x = - 6 into f(x)
f(- 6) = -
× - 6 + 5
= -
+ 5 = 4 + 5 = 9
first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3
