Answer:
25*pi or
78.5 square units.
Step-by-step explanation:
If there was no shaded area, the area of the circle would be pi * r^2
r = 10
Area = pi * 10^2
Area = 100 * pi
Since there is a shaded area, the shaded part looks to be 1/4 of the whole. There's no indication of what it actually is, but 1/4 should be close enough.
Area_shade = 1/4 (100*pi)
Area_shade = 25 * pi
That's one answer.
Another is 25 * 3.14 = 78.5 square units
Answer:
6 shirts
Step-by-step explanation:
The cost of a shirt and 2 ties is ...
$18.50 +2(7.50) = $33.50
For $205, Frank can buy $205/$33.50 = 6.12 sets of shirt and ties.
Frank can buy 6 shirts (and 12 ties) for an amount less than $205.
_____
<em>Additional comment</em>
Frank's cost will be $201 for that purchase.
Step-by-step explanation:
V=pi×r^2×h
36pi =pi × (3)^2 × h
36pi ÷ pi×9 = h
4cm^2 = h
Prime for 2 digit odd number: 13 , 11 , 17, etc
Odd number that is composite: 39, 25, 15, etc
Hope this helps
