Answer:

first one:

Area of a circle = π*r²

diameter (they gave) = 30ft

radius = diameter/2 = 15ft

π*15²= 706.85834705770347865409476123789‬

to nearest tenth= 706.9 ft

second question:

circumference = 2*π*r or d(diameter)*π

diameter = 30ft

30*π = circumference = 94.247779607693797153879301498385‬

in terms of π = 30π

How can a ratio's number can be changed without changing the ratio itself
eimsori [14]
<h2>Answer:</h2>

The ratio is a fraction that tells us how many times longer a thing is compared to another thing. In mathematics, we express a ratio as the relationship between two numbers, namely a \ and \ b, so the ratio can be written as:

r=\frac{a}{b}

If we can change this number without changing the ration we need to multiply  both the numerator and the denominator by the same number. For instance, if we have the following ratio:

r=\frac{2}{3}

We can multiply both the numerator and denominator, say, by 7. Then:

r=\frac{7\times 2}{7 \times 3}=\frac{14}{21}

As you can see, the ratio's number has changed but without changing the ratio itself because:

\frac{2}{3}=\frac{14}{21}

You select a card at random from the cards that make up the word “replacement”. Without replacing the card, you choose a second
musickatia [10]
Replacement = 11 total

probability of choosing a consonant = 7/11
without replacing the card
probability of choosing an e = 3/10

probability of choosing both = 7/11 * 3/10 = 21/110 <===
