The area of a circle A equals either:
πr² or πd²/4
96 = πd²/4 => d = 11 inches
The diameter of the second circle equals :
11*1.5 = 16.5 inches
The area equals: π(16.5)²/4 = 214 square inches
Good luck
Answer:
.797
Step-by-step explanation:
If your talking about a decimal number, you would say the <u>thousandth</u>. I know, weird, but don't blame me.
To round up, any number above 5 rounds up to the next value place, and any number below 5 rounds down to the last value place.
Ex: 1.3483838383
Since 8 is greater than 5, we could get rid of all the 83s and just round up to 1.35.
So the thousandths place in a decimal would be 0.79<u>6</u>66357977, so we just ask if the next number after the thousandths place is greater than 5. The place number after .796 is 6, so since it is greater than 5, we would round up to .797.
Our answer is .797.
Hope this helps!
Answer:
19.5
Step-by-step explanation:
Circumference is radius multiplied by 2, then multiplied by pi.
3.1 × 2= 6.2
6.2 × π= 19.477 ≈ 19.5
π also equals 3.14
You have to replace d woth 3 in formula
7d^2+10=7*(3)^2+10=7*9+10=63+10=73
d is the correct answer
