A = pi(r^2)
1. Calculate radius:
r = d/2, so r = 18
2. Enter variable into equation
a = pi(r^2)
becomes a = 3.14(18^2)
3. Solve
a = 3.14(324)
a ~= 1018 in2
4. Convert to feet
1018/12 = 84 ft2
5. Multiply by unit rate
84(3.5) = $294
It will cost $294 to paint the sign.
Answer:
x=12
Step-by-step explanation:
It is a textbook 3:4:5 triangle. The hypotenuse is 15 (5*3), and the base is 9 (3*3). Since they both share a common factor of 3, the 3rd side would be 4*3, which is 12.
It would be 21/32. To find this out, you would need to first multiply (-7/8) by (-3/4) which would give you 0.65625. Then look at your answer choices and divide each one ( (/) = same as dividing) until you get 0.65625 as one of the values.
Answer:
$5820.07
Step-by-step explanation:
Substitute 243 into the equation for n:
![c=117\sqrt[3]{243^{2} }+1264\\c=117\sqrt[3]{59049}+1264\\c=117*38.9407384+1264\\c=4556.06639+1264\\c=5820.06639](https://tex.z-dn.net/?f=c%3D117%5Csqrt%5B3%5D%7B243%5E%7B2%7D%20%7D%2B1264%5C%5Cc%3D117%5Csqrt%5B3%5D%7B59049%7D%2B1264%5C%5Cc%3D117%2A38.9407384%2B1264%5C%5Cc%3D4556.06639%2B1264%5C%5Cc%3D5820.06639)
Round 5820.06639 to the nearest hundredth:
5820.07
$5820.07
Answer:
8.25475 m
Step-by-step explanation:
pi*r^3 is the formula for a sphere.
Using this, pi is a nmber (about 3.14) and we only don't know the radius, but we know what it equals.
pi*r^3=1,767.1
First divide by pi, then get ride of the cube by cube rooting both sides.
The cube root of 1767.1/pi (remember to cube root both denominator and numberator!!!) is about 8.25475 m
