Answer:
A=2πrh+2πr2 this is the surface are formula of a cylinder. You already know the scale ratio is 2.5 so the answer is (2.5*surface area formula). For the formula just plug in the values for the radius and the height that is given and solve.
Step-by-step explanation:
20 boys signed up
# of girls who signed up was 195% of the number of boys who signed up
Find 195% of 20:
1.95 * 20 = 39
So 39 girls signed up.
To find out what percent of girls who signed up for the play attended the auditions, divide 26 to the total number of girls who signed up:
26 / 39 = 0.666666667
Multiply by 100:
0.666666667 * 100 = 66.6666667%
So approximately 66.67% or 66 2/3%
Answer:
10/53
Step-by-step explanation:
P = no of orange/total = 20/106 = 10/53
Answer:
12/5
Step-by-step explanation:
tan A = opp/adj
For angle theta, 12 is the opposite leg.
13 is the hypotenuse.
We were not given the length of the adjacent leg, but we can use the Pythagorean theorem to find it.
a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 25
The adjacent leg has a length of 5.
tan theta = opp/adj
tan theta = 12/5
Answer: 12/5
