Answer:
195
Step-by-step explanation:
If there are x boys, then there are x+26 girls. Hence, we write the equation,
x+(x+26)=364
Solve for x:
2x+26=364
2x-338
x=169
So there are 169+26 =195 girls
The area of a rectangle is calculated through the equation, V = L x W. That of the circle is equal to V = πr². These areas should be equal,
V = L x W = πr²
Substituting the known values,
2 ft x 11 ft = (22/7)(r²)
The value of r is sqrt 7.
$42,500 because 45900 dividede by 1.08 is 42500
Answer:
16 + 6pi cm
Step-by-step explanation:
We have a square of length 4 cm
A = s^2 = 4^2 = 16
We have 3 semi circles
with radius 2
A semi circle has an area of
1/2 pi r^2 = 1/2 pi (2)^2 = 1/2 (4pi) = 2pi
There are 3 of them
3 * 2 pi = 6pi
Add the areas together for the square and the semicircles
16 + 6pi
Answer:
The volume of hemisphere is <u>19.4 cubic meter</u>.
Step-by-step explanation:
Given:
A hemisphere is with a radius of 2.1 m.
Now, to find the hemisphere volume with radius 2.1 m.
So, we put formula to get the volume of hemisphere:
<u><em>Hence, the rounded to the nearest tenth of a cubic meter is 19.4 cubic meter.</em></u>
Therefore, the volume of hemisphere is 19.4 cubic meter.
