Step-by-step explanation:

d=2r=2·6.1=12.2ft

C =2πr  

C =2(3.14)(6.1)  

C=2(19.154)  

C= 38.3

Answer:

d= 12.2 C= 38.3

Step-by-step explanation:

The radius of a circle is half of the diameter so multiply 6.1 by 2

6.1 x 2 = 12.2 ft

To find the circumference:

C = 2πr

C = 2(3.14)(6.1)

C= 2(19.154)

C= 38.3

For the formula F = 95K – 455.67, what is the value of K when F = 0?
Inessa [10]

Answer:

<em>K = 4.8</em>

Step-by-step explanation:

<u>Equation Solving</u>

We are given the equation:

F = 95K - 455.67

We are required to find the value of K when F=0:

95K - 455.67 = 0

Adding 455.67:

95K = 455.67

Dividing by 95;

K = 4.8

Can someone please help me on this question! Thank you very much!!
Elis [28]
First find the area of the triangle (on top) and then subtract the area of the circle (on bottom) since the triangle is Equilateral, you can assume that the height can be found by using the 30 60 90 angle relationship. To find the radius of the circle, divide the height by 2.

A group of friends were working on a student film that had a budget of $1140. They used 65% of their budget on costumes. How muc
Stells [14]

Answer:

They use 741 dollars

Step-by-step explanation:

Write 65% as

65/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

65/100 of 1140 = 65/100× 1140

Therefore, the answer is 741

If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.
