Answer:
Area = 64π
Area \: = \pi {r}^{2}Area=πr
2
64 \: \pi \: = \pi {r}^{2}64π=πr
2
{r}^{2} = \dfrac{64\pi}{\pi}r
2
=
π
64π
{r}^{2} = 64r

=64
r \: = \: \sqrt{64} = 8r=
64
=8
Radius = 8 units
Finding the Diameter -
Diameter = Radius x 2 = 8 x 2 = 16 .

Step-by-step explanation:
a₆ = a₇+(6-7)d = -4 -(-5) =1
After the division, we get 8.99031476998. This rounds to <u>9</u> as a whole number, which is the answer.
When rounding to a whole number, the digits following the decimal decide what number it rounds to. If it is 0-4 it rounds to whatever the whole number currently is E.G.
8.1 would round to 8
But if its 5-9 it rounds to one above, like in our current case.
8.5 rounds to 9.
42.414 rounds to 42.
42.94149124 rounds to 43.
