From the diagram we have
Base =
Height =
Area = Base × Height
126 =
⇒ Expand the double bracket
126 =
⇒ Subtract 126 both sides
0 =
⇒ Factorise the quadratic expression
0 =
⇒ Equating each factor to zero
We need the positive value of
so we use
Height = 5+1 = 6
Base = 4(5)+1 = 21
Answer:
262 in
Step-by-step explanation:
the equation for volume of a sphere is : 
r
so replacing the number of the radius into the equation, it would look like:
r
which gives you 523.59878 in
but since it's a hemisphere, you'd divide it in half, which gives you 261.79939.
since you're rounding off to the nearest whole number, you're answer is 262 in
<span>We could use 7+7=14 to find the sum of 6+7.
<u><em>Explanation</em></u><span><u><em>: </em></u>
7+7=14 is one of the two closest doubles to 6+7.
We know that:
7 is 1 more than 6; this means:
7+7 will be 1 more than 6+7.
7+7=14, so finding 1 less,
6+7=13.</span></span>
A net is pretty much a three dimensional shape unfolded into a flat construction. Imagine cutting the edges of a box and unfolding it so you can lay it flat on the ground. That would form a net for the 3D shape of the box.
In this case, 1 and 2 obviously aren't right since they would both involve triangles in their net. 3 is close, but the parts of the net wouldn't be completely equal. Therefore it has to be 4, the cube.
0.4 because if it’s five or more, add one more. If it’s four or less, let it rest.
