64*65 =4,160... :-)
Cross multiply
here you go! hopefully this helps :))
Step-by-step explanation:
take the base square. find the diagonal
16^2+16^2 = 2*16^2= d^2
d= 16√2
half of the diagonal will form the baSe of right triangle of hypotenuse 10. but the base will be 8√2 which is greater than 10. so I feel the slant hr has to be different and more than 10
You subtract 6 from both sides, and then multiply by 6 on both sides. You should get -20.
Answer:
72π (I think)
Step-by-step explanation:
Think of it in terms of the entire circle. A semi-circle is just half a circle, so the area of a semicircle will be half of the area of the entire circle. The radius of the semicircle is 6, so the radius of the whole circle is 12. Then, we can do to get the area of the semicircle is 72π. I'm pretty sure that's right. Let me know if I made a mistake somewhere.
