7 0

Step-by-step explanation:

The formula for the area of a circle is pi x radius squared. So since we know the diameter we can take that and half it giving us radius. Than we plug radius in the formula, so 6.5 squared is 42.25. You than multiply it by pi, and not 3.14 because theirs a possibility of being a couple units off when rounding, and after multiplying it you'll be left with the answer of 132.73

Answer: 132.73

Sever21 [200]

Answer:

Ethan rollerbladed each day $\frac{623}{d}$ kilometers.

Step-by-step explanation:

Given:

Ethan rollerbladed a total of 623 km over d days.

Now, to find the kilometers Ethan rollerblade each day.

Total number of distance rollerbladed = 623 km.

Total number of days = $d.$

<u><em>As, Ethan rollerbladed each day the same distance.</em></u>

Now, to get the distance Ethan rollerbladed in each day we divide total number of distance rollerbladed by total number of days:

$Ethan\ rollerbladed\ each\ day\ =\ \frac{Total\ number\ of\ distance\ rollerbladed}{Total\ number\ of\ days}$

$Ethan\ rollerbladed\ each\ day\ =\ \frac{623}{d}$

Therefore, Ethan rollerbladed each day $\frac{623}{d}$ kilometers.

What is 1/4 plus 1/3, will give brainliest and thank you and rate and give 15 points plz help

Slav-nsk [51]

First, you have to convert 1/4 and 1/3 to have the same denominator.

So, 1/4 x 3 = 3/12. 1/3 x 4 = 4/12.

Now, you can add 3/12 + 4/12 = 7/12.

Find the measure of an angle such that the difference between the measures of its supplement and four times its complement is 30

Katarina [22]

Answer:

70 degrees

Step-by-step explanation:

x = angle

180 - x = it's supplement

90 - x = it's compliment

(180 - x) - 4(90 - x) = 30

180 - x - 360 + 4x = 30

reducing

3x = 210

x = 70
