Divide 30 by 10. 30mph/10seconds = 3mph/seconds
It would be A=18 because of the equation a^2+b^2=c^2.
Answer:
the answer is B
Step-by-step explanation:
If the face is a square, then (l*l)
If the face is a triangle, then (b*h)(1/2)
If the face is a rectangle, then (l*w)
If the face is a circle, then (r²)(3.14)
You can then add all these faces up to get the total surface area of the prism.
