Answer:
B) 9π in^2
Step-by-step explanation:
Circumference of a circle is C = πD
Divide 6π by π to get 6 then divide by 2 to get the radius of the circle
Area of a circle is A = πr^2
6/2 = 3 3 = r
π(3)^2 = 9π
Answer:
The 1st one
Step-by-step explanation:
Answer:
The solution is obtained by dividing the number of flowers by the number of vases.
Step-by-step explanation:
The story problem is very straightforward. Normally, you need to read the problem and understand it.
Let's look at the question again.
Although we do not have all the quantities, we can still show how to solve the problem.
Let x be the total number of flowers.
There are 4 vases.
Therefore, the number of flowers in each vase will be:
x/4
Flow the same rule for similar problems.
Hello from MrBillDoesMath!
Answer:
x = 27
Discussion:
Triangle DQC and DBR are similar by AAA so corresponding parts have the same ratio.
x /(x+18) = 39 /(39 + 26) =>
x/(x+18) = 39/65 => as 39 = 13*3 and 65 = 13 * 5
x/(x+18) = 3/5 => cross multiply both sides by x+18
x = (3/5)*(x+18) => multiply both sides by 5
5x = 3(x+18) =>
5x = 3x + 54 => subtract 3x from both sides
2x = 54 =>
x = 27
Thank you,
MrB
