circumference of a circle (C)

C = πd or 2πr ( because d 2 x r)

r= 18 miles given

d= diameter

r= radius

d = 2 x r

d = 2 x 18 = 36 miles

2) C = πd

C = 3.14 x 36 = 113.04 miles

3) approximate measure of C = 22/7 x 36= 113.14 miles

Describe how to find the scale factor if an antenna is 60 feet long and a scale drawing shows the length as 1 foot long. Please
bekas [8.4K]
The actual is 60 feet long, the drawing is only 1 foot long. So the scale factor must be 1/60. You know that the scale factor has to be less than one in this case because you're going from a bigger measurement to a smaller measurement(60 to 1).

A blue jay lives in a nest that is 12 meters high in a tree the blue jay flies 15 meters to get from its nest to a flower on the
Ivan

Answer:

The distance between the base of the tree and the flower is 9m

Step-by-step explanation:

Here, we have to paint a picture.

The flower is on the ground, the height of the tree is 12m.

The distance from the nest to the flower on the floor is 15m

Indisputably, what we have is a right angled triangle, with the height being 12m, the length of the hypotenuse being 15 and we are asked to calculate the adjacent which represents the distance from the base of the tree to the flower

To get this distance, we simply apply the Pythagoras’ theorem which states that the square of the hypotenuse(longest side of the triangle) is equal to the sum of the squares of the other two sides.

Thus mathematically, we know that our hypotenuse is 15m and the height is 12m

The length we are to calculate is the adjacent and it is equal to;

15^2 - 12^2

= 225 - 144

= 81

The length is thus

√(81) = 9m

Please check attachment for a diagrammatic picture of the triangle

Dan invests £18790 into his bank account. He receives 5,3% per year simple
earnstyle [38]

Answer:

697109 pennies

Step-by-step explanation:

First, you use the formula A = P (1 + rt).

R= rate which is 5.3%

T= time which is 7 years.

P is the principle which is 18790

A= is the answer

so first you multiply 7*5.3% which you get 0.371

then you multiply that with 18790 which then you get 6971.09

if you want pennies you multiply it with 100 to get 697109
