Answer: 166.67π
Step-by-step explanation:
150/360 x π x 20²
Because the answer is in pi, we times 150/360 by 20² and pop the pi sign next to it
150/360 x 20² = 166.66667
and when we put the pi sign it is
166.67 π
3/4b-1/6=1/2×b
1.75b=.3
b=0.2
I believe this is right. But not 100%
17) 11.1
18) 21.4
19) 30.5
20) 16.5
21) 26.5
Answer:
16
notice how a right triangle was formed, and the Pythagorean theorem could be used to solve this :
a^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 64
a= 8
multiply it by 2 to get the side of the base
8 * 2 = 16
Hey there!
The answer is false. A 90 degree angle is called a right triangle. Any angle less than 90 degree is called an acute angle. Any angle more than 90 degree is called an obtuse angle
