First, you've got to figure out the value of the radius so divide the diameter by two. Then, you'll want to find the area of the base or pi times radius squared.
(3.14x3^2)x9=V
After doing the math your answer comes out to 254.34 cubic feet or feet^3
Answer:
6 7/12
Step-by-step explanation:
We need to get a common denominator, which is 12
12 1/4 - 5 2/3
12 1/4*3/3 - 5 2/3*4/4
12 3/12 - 5 8/12
We will need to borrow from the 12 since 3/12 is less than 8/12. Write the 1 we borrow as 12/12
11 + 12/12 + 3/12 - 5 8/12
11 15/12 - 5 8/12
6 7/12
An arc is a part of the circumference of a circle and the angles that subtend the arcs are proportional to the length of the arc.
So, you basically have two arcs to compare: a 10cm arc and a 60cm arc. But the 60cm arc also happens to be the circumference in this case, so you know that the angle that subtends that arc is 360 degrees (the whole circle). The 10cm arc is 1/6 of the whole circumference so the angle is going to be 1/6 of 360 degrees, which is <span>60 degrees.</span>
Since it as at the same time and place.
Let x be the length of the shadow of the 40-ft pole.
The ratio from 30 and 8 would have to be the same as 40 and x.
30:8 = 40:x
30/8 = 40/x Cross multiply
30x = 40*8
x = 40*8 / 30 = 32/3 = 10.67
Length of shadow for 40ft is 10.67 ft.
