The area of circle B is 121 times greater than the area of circle A. The radius of circle B is 44. What is the radius of circle

xxMikexx [17]

Formula:
$\bigg( \dfrac{radius_1}{radius_2} \bigg)^2 = \dfrac{area_1}{area_2}$

Plug in the values:
$\bigg( \dfrac{r}{44} \bigg)^2 = \dfrac{1}{121}$

Simplify LHS:
$\dfrac{r^2}{1936} = \dfrac{1}{121}$

Multiply by 1936 on both sides:
$r^2 = \dfrac{1936}{121}
$

Simplify RHS:
$r^2 = 16$

Square root both sides:
$r = 4$

Answer: The radius is 4 units. (Answer B)

There are as many 5p coins as 1p coins in the bag.

nekit [7.7K]

Answer:

160

Step-by-step explanation:

In math, the word of means multiply. :)

3/8 * 640 = 240, so there are 240 1p coins.

there are the same number of 5P coins, so there are 240 5p.

640 - 1p - 5p = 2p

640-240-240 = 160, so there are 160 2p coins.
