If the exact length is s, you have
.. s = r*θ . . . . θ = π/2
.. r = s/θ
.. r = 2s/π

Fill in the exact length for "s" in the formula and compute to find the radius.

The weather forecast says there’s 70% probability of rain tomorrow. What are the odds against rain
krok68 [10]

Answer:

30%

Step-by-step explanation:

<u>Key</u><u> </u><u>skills</u><u> </u><u>needed</u><u>:</u><u> </u><u>Probability</u>

1) There is a 70% chance of rain.

2) We need to find the chances against rain.

3) To do this, we need to use the fact that

70% + x = 100% (Since all the probabilities add up to 1 or 100%)

4) If you subtract 70% from both sides, x = 30%

5) This means the probability against rain is 30%.

Find the surface area of the following in cubic inches.
Alenkasestr [34]

Answer:

427.04 in²

Step-by-step explanation:

Surface area = 2\pirh + 2\pir²

A = 2\pi (8)(0.5) + 2\pi 8^2

A = 2\pi 4 + 2\pi 64

A = 25.12 + 401.92

A = 427.04

So, the surface area of the cylinder is 427.04 in² which is answer choice D.
