Answer:
First lets find the area of the bottom circle:
7.2 is your radius so:
7.2^2 = 51.84 the reason why you square your radius is because thats apart of the formula when finding the are of a circle.
lets continue:
51.84 x 3.14(pi) = 162.7776
Now we need to find the area of the round surface but first we need to find the circumference of one circle and multiply it by the height.
2 x 3.14 x 7.2 = 45.216
Now lets multiply it by the height:
45.216 x 17 = 768.672
Now lets add both areas:
768.672 + 162.7776 = 931.4496 dont forget to round to the nearest hundredths place! 931.4496 rounded up = 931.45 square meters is your answer.
Presumably,
. In that case,
(A)
The average rate of change over the interval
is
and over
, it's
(B)
, i.e. the average rate of change over the second interval is 25 times higher. That's to be expected;
is an exponential function. As
gets larger, the rate of change of
gets larger too.
The earth travels 1,050 miles in an hour.
There are 24 hours in a day.
So multiply 1,050 by 24.
And you get 25,200.
The earth travels 25,200 miles in a day.
Answer:
[(cosθ-1)^2]/(sinθ)^2
Step-by-step explanation:
(cotθ-cscθ)^2
(cotθ)^2-<em>2cscθcotθ</em>+<u>(cscθ)^2</u>
(cosθ/sinθ)^2-2<em>(cosθ/(sinθ)^2) +</em><u>1/(sinθ)^2</u>
All have same denominator, (sinθ)2, add/subtract
((cosθ)^2-2cosθ+1)/(sinθ)^2
Factor the top
[(cosθ-1)^2]/(sinθ)^2
