8.01-(2.2+4.67) ->
8.01-(6.87) ->
1.14 is the answer.
The diameter of the table is 42 inches. The radius of the table is half of the diameter of the table, so the radius of the table is 42/2 = 21 inches.
Add on 8 inches to the table radius to get: 21+8 = 29
So the radius of the table cloth is r = 29
Plug this into the area of a circle formula
A = pi*r^2
A = pi*29^2
A = pi*841
A = 841pi
A = 841*3.14
A = 2640.74
The approximate area of the table cloth is 2640.74 square inches.
Answer:
5. x= 13 y= 18.4
6.
Step-by-step explanation:
question 5:
tan45=x/13
multiply both sides by 13 to get x by its self.
end up with 13×tan45 so put that in the calculator to get x
then you do cos45= 13/y
multiply by y on both sides.
end up with y×cos45=13
divide the cos45 by both sides
put 13/cos45 to get y
question 6:
sin30=4/x
multiply x on both sides
end with x×sin30 =4
divide sin30 on both sides
put 4/sin30 in a calculator to get x
same thing again but with tan30 ahaha
