To find the circumference of a circle you use the formula, C=2*pi*radius or C=pi*diameter, in his case you would use the first option, C=2*pi*radius, because the radius is the given value. You then plug the values into the equation to solve for the circumference...
C=2*pi*15
C=30*pi
C=30pi or approximately 94.2478
Answer:
<u>2,592,100 m³</u>
Step-by-step explanation:
<u>Volume of Square Pyramid</u>
- V = 1/3a²h
- V = 1/3(230)²(147)
- V = 49 x 52900
- V = <u>2,592,100 m³</u>
Answer:
z=70, y=102
Step-by-step explanation:
180-110 = 70
so, z=70
99+89+70 = 258
360-258 = 102
so, y=102
