So, for the area of a circle, there should be a line in the middle. Correct?
Well, that line is the diameter. Then cut that in half, so if the diameter is 6, the radius is 3.
Then multiply the the radius by the radius, so 3x3 once you get that, multiply the answer by pi. Pi= 3.14, so if you do 3x3x3.14 you should get 28.26. Hope this helps.
Answer:
1 sandal= $7
1 flip flop =$2.5
Step-by-step explanation:
say one sandal costs x and one flip flop costs y
3 x+y=23.50
4x+2y=33
solve using simultaneous equationsto find the values of x and y
Answer:
its 5%
Step-by-step explanation:
6600-5%= 6270
6600-6270= 330
for number 5, you take the area of the area of the fountain, which is pi * radius squared. this is equivalent to 3.14 * 4^2. then to simplify I made it 3.14 times 16 and then got the answer of 50.24. Then you take the area of the fountain plus the path, which makes the diameter 9.5 divide that by 2 to get the radius, which is 4.75. pi * 4.75^2 is about 70.85. then you subtract the two(70.85-50.24) to get 20.61. since its 10 dollars per square meter, you multiply 20.61 by 10 to get 206.10 dollars. That is your answer.
