Answer:
Step-by-step explanation:
We can use the relationship between a radius and a diameter to find which circle has a greater area without calculating it.
We know that the diameter is twice the size of the radius.
- The diameter is the distance across the circle at the center
- The radius is the distance from the center of a circle to the edge
Using this, we can find the radius of a circle that has a diameter of 6.
Since the diameter is twice the radius, the radius will be half the diameter.
Since the diameter is 6, the radius is 3.
Circle areas can be calculated with the following formula, where r is the radius:
Using this, we know that a higher value of r will get us a greater area. Therefore, we know that the greater value (3 or 4) will get us the greater area.
Since 4 is greater than 3, we know that the circle with the radius of 4 (Ava’s) will have a greater area.
Hope this helped!
Answer:
He can drive 481 miles if David rents his car for three days
Step-by-step explanation:
This is true because if you take the 24.95 and multiply it by 3, because he rented it for three days, you'll get 74.85. Then you'll subtract 200 (the total money that can be spent) by 74.85 you'll get 125.15. Divide the remaining number, 125.15 by 0.26 to get 481.34. Take the decimals away because you don't need it, if you want to be sure it's correct you can multiply 481 by 0.26 to get 125.05 which is lower than 125.15 so it good because if you use 482 besides 481 it will be higher than the amount of money David can spend, that's why 481 is the right answer.
To order these, you need to find the lowest common denominator, which is 64. Now you need to make all them have the same denominator.
1/2 = 32/64
5/16 = 20/64
30/64 = 30/64
3/8 = 24/64
9/32 = 18/64
Now just look at the second column and look at the top(first) number to order them.
The order from least to greatest:
9/32, 5/16, 3/8, 30/64, 1/2
Answer:
=11/4 cm
Step-by-step explanation:
We are finding the perimeter
P = 2(l+w)
l = 3/4 cm
w = 5/8 cm
The common denominator is 8
l = 3/4 *2/2 = 6/8
P = 2(6/8+5/8)
=2(11/8)
=22/8
=11/4 cm (2 1/4 cm)
It says an integer or a fraction, not a mixed number
