Answer:

See below.

Step-by-step explanation:

She is wrong because 3 times the perimeter of one triangle is the sum of 9 sides of the triangles.

In the shape we see that some of the sides of the triangles are 'shared' and dare not part of the perimeter of the shape, - the perimeter is only the length of 5 sides of a triangle.

So the perimeter is less than the sum of the sides of the 3 triangles.

Answer:

Jemima is wrong because perimeter is sum of all sides and the perimeter of this figure would be the outer sides of it and not the inner sides.

The volume of a cylinder is given by the formula V= πr^2h, where r is the radius of the cylinder and h is the height. Suppose a

AfilCa [17]

Answer:

V=π*(2x^3+35x^2+176x+192)units^3

Step-by-step explanation:

V=πr^2h

r=x+8

h=2x+3

V=π*(x+8)^2*2x+3

=π*(x^2+16x+64)*2x+3

=π*(2x^3+32x^2+128x+3x^2+48x+192)

=π*(2x^3+35x^2+176x+192)

Volume of the cylinder=π*(2x^3+35x^2+176x+192)units^3

Find the circumference of a circle with an area of 113.1 in square

nlexa [21]

Step-by-step explanation:

$Circumference = 2r\pi \\Area = r^2\pi$

In order for us to find the circumference, we need to find the radius from the given area by rearranging the area formula.

$r=\sqrt{\frac{A}{\pi } }$

$r=\sqrt{\frac{113.1}{\pi } }$

$r=\sqrt{36}$

$r=6$

Now that we have the radius, we can find the circumference.

$Circumference=2(6)\pi$

$Circumference=12\pi$

$Circumference=37.68$

So, when given 113.1 in sq for the area, the circumference of the circle is 37.68 in.
