Priya drew a circle whose area is 25 cm. Dan drew a circle whose diameter is 4 times the radius of Priya's circle. How many time
Vitek1552 [10]

Answer:

400

Step-by-step explanation:

first work out the radius of priya's circle with the equation a = \pi r^{2}

25 = \pi r^{2}

\frac{25}{\pi } = r^{2}

r = \sqrt{\frac{25}{\pi } }

we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x\sqrt{\frac{25}{\pi } }

this means that if the diameter of dan's circle is 4 times bigger it must be

8x\sqrt{\frac{25}{\pi } }

to find the radius of dan's circle we divide the diameter by to 2 to give

4x \sqrt{\frac{25}{\pi } }

then use the a=\pi r^{2} equation again

a= (4 \sqrt{\frac{25}{\pi } })^{2} \pi

which equals 400

hope that helped

Me. Watson is making 34.6 fluid once's of red paint and 18.6 fluid ounces of yellow paint to make orange paint. How many 3.5- fl
forsale [732]

Answer: She can fill about 15 3.5- fluid once jars.

Step-by-step explanation:

Given:

Quantity of red paint = 34.6 fluid ounces

Quantity of yellow paint = 18.6 fluid ounces

Total quantity of orange color = (Quantity of red paint )+(Quantity of yellow paint )

= (34.6+18.6) fluid ounces

= 53.2 fluid ounces

Number of 3.5- fluid ounce jars she can fill = (Total quantity of orange color) ÷ 3.5

= 53.2÷3.5 = 15 (approx)

Hence, She can fill about 15 3.5- fluid once jars.
