Estimate 2.8 divided by 6

2 answers:

Answer:

1/2 or 0.5

Step-by-step explanation:

Since this question is asking for an estimate, you have to round 2.8 to the nearest whole number. 2.8 is closer to 3 rather than 2. Since 6 is already a whole, divide 3 by 6, which is 1/2 or 0.5. If you were to solve this problem without estimating, you would get 0.4666666666, which rounds to 0.5, but the question asks for an estimate.

Hope this helps!

2.8 ÷ 6 = 0.4666666.... it will continue
The estimate would be the round off of the Actual answer which would be 0.5 since 0.46666.. is closer to 5

The area of a cross section through the center of a sphere is 46 square inches. Find the surface area of the sphere.

gavmur [86]

Answer:

184 in.^2

Step-by-step explanation:

The cross section through the center of a sphere is a circle whose radius is equal to the radius of the sphere.

area of circle

$A_{circle} = \pi r^2$

$\pi r^2 = 46$

$r^2 = \dfrac{46}{\pi}$

$r = \sqrt{\dfrac{46}{\pi}}$

$r = 3.83 ~in.$

surface area of sphere

$SA = 4 \pi r^2$

$SA = 4 \times \pi \times (3.83)^2$

$SA = 184~in.^2$

Artyom0805 [142]

You can use scale to solve. 5185/8.5=610

4845/610= about 8 hours.
