Step-by-step explanation:
1. radius=13in
diameter= 2r =2(13)=26in
area=πr²= 22/7*(13)²
531.14in²
circumference= 2πr=2*22/7*13
81.71in
2.radius=32ft
diameter= 2r =2(32)=64ft
area=πr²= 22/7*(32)²
3218.28ft²
circumference= 2πr=2*22/7*32
201.14ft
Answer:
A. 45°
Step-by-step explanation:
The smallest interior angle measure of any regular polygon is that of an equilateral triangle: 60°.
___
The corresponding exterior angle measure for interior angle x will be its supplement: 180° -x. This value must be a divisor of 360° 360° is not evenly divisible by 180°-45°=135°.
Answer:
B
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
y + 10 + 2y + 50 = 180 , that is
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40 → B
