Answer:
x = 5.744 (3dp)
Step-by-step explanation:
Pythagorus' Theorum
7^2 - 4^2 =
49 - 16 = 33
x = sqrt of 33
x = 5.744 (3dp)

10* (1/5)
= 10/5
= 2
The final answer is 2~
The formula of cone's capacity is V = (1 / 3) (pi x r x h)
we know that r = 3.5, we must find h, the slant height is H=6.5, applying pythagorean theorem h ^2 = H^2, so h= sqrt (H^2 - r^2)
h = sqrt (6.5^2 - 3.5^2) = 5.47
finally, V = (1 / 3) (3.14 x 3.5 x 5.47) = 20.03 cm^3
the surface are is A = pi x r x H = 71.43 cm^2
90-x because a complementary angle is =90 degrees.
Answer:
c
Step-by-step explanation
because 2 is the y intercept and 3 is the slope so you plot (0,2) than do the slope.
