I believe the answer is b= -5
Answer:
9/16
Step-by-step explanation:
First we need to know that the dimensions ratio, the surface area ratio and the volume ratio have the following relation:
volume ratio = dimension ratio ^3
surface area ratio = dimension ratio ^2
The volume ratio between small prism and the large prism is 27 / 64.
To find the dimensions ratio, we need to take the cubic root of the volume scale:
dimension ratio = 3√(27/64) = 3/4
Now, to find the surface area ratio, we just need to make the square of the dimension ratio:
surface area ratio = (3/4)^2 = 9/16
Answer: A
Step-by-step explanation:
Answer:
<h2>✓6 divided by 5 is 1.2, so 1.2 radians.</h2>
Step-by-step explanation:
<h3 /><h3>The circumference of the circle of 5 cm radius equal 2(pi)r= (2*22*5)/7=31.42857143cm and this =2(pi) radias.</h3>
<h3>So a 6cm are of the same circle will subtend(6/ 31.42857143)*2(pi) radians= 1.2 radians at the center of the cercle.</h3>
