. Cost. A circular terrace has a radius of 6 ft. If it costs $1.50 per square foot to pave the terrace with brick, what will the total cost be?​

The total cost will be 9 dollars

Step-by-step explanation:

1.50 (price) times 6 (radius) is 9 All I did was multiply 1.50 by 6 and the answer was 9.

$169.65 is the total cost

Step-by-step explanation:

A= πr2= π·6(2)≈ 113.1

113.1 * 1.50 = 169.65

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

7

step-by-step explanation:

the answer would be 7
