Answer: -1
Step-by-step explanation:
I assume the points are (-3, r) and (9,2).
Substituting into the slope formula,
Answer:
39 to the nearest degree.
Step-by-step explanation:
tan y = opposite side / adjacent side = 8/10 = 0.8.
So y = 38.660 degrees.
All you gotta do is type on a calculator it’s easy
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.
