Answer:
C)
Step-by-step explanation:
As it is 60 degree, and the whole circle is 360 degree, so we need to find 1/6 of the circumference of a circle, as C = 2*pi*r = 2*pi*3 = 6pi and 1/6 of it is pi.
Answer:
7 months.
Step-by-step explanation:
1250-800=450. so more than 450 has to be spent and that comes out to 7 months where you'll spend 455
Answer:
B
Step-by-step explanation:
Seeing as the change is consistent within the vertices, this would be correct.
By definition of the trig functions,
We have , so , and , so .
Just to check: we should have
by the Pythagorean theorem. Indeed,
Answer:
152
Step-by-step explanation:
Hello there!
The prism shown is a triangular prism
There are many different formulas for solving for the surface area of a triangular prism but I am going to use the most simple one
Formula: SA = bh + L(s1 + s2 + s3) (found in the image)
b = base length
h = height
L = length
s1 = (same thing as the base length)
s2 and s2 = other triangle side lengths ( the base is an isosceles triangle so they are equal to each other.)
The triangular prism has the following dimensions
b = 6
h = 4
L = 8
s2 and s3 = 5
Now that we have identified each dimension we plug in the values into the formula
SA = 6*4 + 8(6+5+5)
6*4=24
8*6=48
8*5=40
40*2=80
80+48=128
128 + 24 = 152 so the surface area of the triangular prism is 152 cm²
