The table shows the temperature of a substance at the start of a science experiment which - 16.8°C and we were told that it changed by 3/4 of the value which therefore means that the final temperature at 2:35pm is - 29.4°C.

This is referred to as the degree of hotness or coldness of a substance and it is measured in Celsius, kelvin etc.

In this scenario we were told that the temperature - 16.8°C changed by 3/4 of the value which means that:

3/4 × - 16.8°C = - 12.6°C

The temperature at 2:35pm will therefore be  - 16.8°C - 12.6°C = - 29.4°C.

Therefore , the solution to the given problem of circle comes out to be  

572 yard^2.

Each point in the plane that is a certain distance from some other point forms a circle (center). Thus, it is an curve composed of spots that are spaced apart from one another in the plane. Additionally, at every angle, it is axis of rotation symmetric about the center. The closed, two-dimensional plane of a circle has every pair of points uniformly separated from the "center." With tracing a path through the circle, one can create a line of circular symmetry. Additionally, at every angle, it is radially symmetric about the center.

Here,

A parabola is an approximately U-shaped, mirror-symmetrical planar curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.

One definition of a parabola includes a line and a point (the focus) (the directrix). The directrix is not the main focus. The locus of points in that plane that are equally spaced apart from the directrix and the focus is known as the parabola.

Given a horizontal parabola centered on the origin opens to the left,

The circumference of circle B is 14 m

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here: The circumference of circle A as 2²/₃ m and circumference of circle B as 1¹/2 times the diameter of circle A

let the radius of the circle A be r then we have

2πr=8/3

r=4/3×7/22

r=14/33 m

or diameter of the circle A= 28/33
