Answer:
9420 ft
Step-by-step explanation:
First find the circumference to find the distance around
C = 2 * pi *r
C = 2 * 3.14 * 15
94.2
Then it makes 100 revolutions
94.2*100 =9420
Answer:
x = 7
Step-by-step explanation:
The larger triangle is twice as big as the smaller triangle. Therefore, the length of the side EF is twice as large as the side YZ.
I multiplied 4.5 (the length of YZ) and 2 to get 9. The value of side EF is 3x-12 and should be equivalent to 9.
3x - 12 = 9
I solved this equation by adding 12 to both sides and dividing 3 on both sides.
The value of x is 7.

Answer:
A. 2
Step-by-step explanation:
The perimeter is the sum of the side lengths:
48 = (3t +3t) +(4t +4t) +(7t +6)
42 = 21t . . . . . . . . . . . . . . . . . . . collect terms, subtract 6
