Agrasshopper is 99 mm while a cockroach is 7 cm . what is the difference in length between the insects

29 mm or 2.9 cm

Step-by-step explanation:

Given : The length of grasshopper = 99 mm

The length of cockroach = 7 cm

We know that 1 cm = 10 mm

Then , the length of cockroach = 70 mm

Then , the difference in length between the insects is given by :-

Therefore , the difference in length between the insects = 29 mm or 2.9 cm

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

answer: .64
