Answer: 133/2π
Step-by-step explanation:
<u>Area of ends:</u>
Area of Circle = πr²
π3.5²=49/4π
There are two ends so you multiply that by 2 to get 49/2π
<u>Area of Rest:</u>
First, you need to find the circumference using the equation: πd
πx7=7π
Then to find the area you just need to multiply 7π by the height
7π x 6 = 42π
<u>Total surface area</u>
You now just need to add them together
49/2π + 42π = 133/2π
Answer:
68°
Step-by-step explanation:
sum of interior angles in a parallelogram is 360. two side must form 180 degrees and the opposite side are equal
Answer:
27 : 100
Step-by-step explanation:
Given :
__________ no cold ____ cold _____ total
Vitamin C ___ 41 ________ 15 ______ 56
Zinc _______ 12 _________5 ______ 17
Echinacea __ 21 _________ 6 ______ 27
Total ______ 74 _________ 26 ____ 100
The ratio of people who took Echinacea :
Number of people who took Echinacea : total number of people in the survey
From the TOTAL column:
Number of people who took Echinacea = 27
Total Number of people in survey = 100
Hence, ratio equals :
27 : 100
This can be solved using the
angle bisector theorem. Note that line segment AD is the angle bisector of triangle DAB from angle DAB. Therefore, we know that the ratios
and
are equal. Solving, we get
. Cross multiplying, we get
, and solving this equation we get
.
10.2 is your answer.
circular cardboard with an area between 154 in² and 616 in²
Radius is between 7 inches and 14 inches. ⇒ A) 7 < r < 14
√18 + √2 = √9 *2 + √2 = 3√2 + √2 = (3+1) √2 = 4√2
D) It is irrational and equal to 4 multiplied by the square root of 2.
