Answer:
819.54 cm^2
Step-by-step explanation:
We are given
Slant height = l = 20cm
and
Diameter = d = 18 cm
We have to find radius first
r = d/2 = 18/2 = 9 cm
The formula for surface area is:
As second option is nearest to calculated answer, it is the correct option ..
Answer:
3c=273
c=91
2c= 212
C= 106
c= 91+ 106= 197
so they will need 197 canoes total
Why:
So first you have to determine a set variable to represent the number of canoes, I chose C. Then you make an equation to represent the number of canoes 273 people will use if they group into 3's, from this I got 3c=273. Solve for C and get 91.
The remainder of the group which is 485-273= 212 will use canoes in groups of 2's. To represent this, 2c=212. Solve for C and get 106. Combine 106 and 91 to get the total number of canoes.
Answer: I think its 63−332+45−6
Step-by-step explanation:
Answer:
525 x 1,050
A = 551,250 m²
Step-by-step explanation:
Let 'L' be the length parallel to the river and 'S' be the length of each of the other two sides.
The length of the three sides is given by:
The area of the rectangular plot is given by:
The value of 'S' for which the area's derivate is zero, yields the maximum total area:
Solving for 'L':
The largest area enclosed is given by dimension of 525 m x 1,050 and is:
Parallel lines NEVER intersect/meet, this is because they have the same slope and they go in the same direction.
These lines are parallel because they have the same slopes of 3/4 (because they go 3 units up and 4 units to the right. slope = rise/run)
