Answer:
<h2>132.25π m²</h2>
Step-by-step explanation:
The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.
then
by equating the last two expressions we get: 23π = 2πr then r = 23/2
then
the area = π × r² = (23/2)²×π = (132.25)×π
Answer:
Final cost of ticket = $205
Step-by-step explanation:
Speed limit is given: 60 miles per hour
Car travelling at a speed of: 78 miles per hour
Car is exceeding speed limit by: 78 - 60 = 18 miles per hour
We are given that the dine ticket includes $25 plus $10 for each mile over the speed limit:
Final cost of ticket = $25 + (miles over speed limit * 10)
= 25 + (18*10)
= 25 + 180 = $205
To figure this out, you need to multiply all the dimensions together. 100x30=. 3,000cm and 3,000x12= 36,000 cubic centimeters. So now you can divide the 36,000 by 1000 to get the amount of liters the entire tank can hold. 36,000/1000= 36 liters. And because you want to know how much half of the tank is, you divide 36 by 2 and get 18 liters
So 9 x 8 = 72
72/2 = 36
36 x 10 = 360
so 360in
Hope this helps
The uppercase T means "transpose". A matrix transpose is where you swap the rows and columns. Anything that is row becomes a column, and vice versa. What this means is that instead of a row vector, you end up with a column vector. The dimensions are important so you can properly multiply matrices.
