Answer:

arc = 15π

Step-by-step explanation:

The arc is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{225}{360}$ ( r is the radius )

given diameter = 24 then r = 24 ÷ 2 = 12

arc = 2π × 12 × $\frac{5}{8}$

= 24π × $\frac{5}{8}$

= 3π × 5

= 15π

How many times larger then 2x10² is 2x10⁸

Brrunno [24]

Answer:

1,000,000 times larger

Step-by-step explanation:

2 x $10^{8}$ = 200,000,000

2 x $10^{2}$ = 200

200,000,000 divided by 200 is 1,000,000

It can also be solved by subtracting the exponents from 10. Then dividing the two number being put the scientific notation.

$10^{8} - 10^{2}$ = $10^{6$

2 ÷ 2 = 1

Now solve:

1 x $10^{6$ = 1,000,000
