<u>Answer:</u>
<u>Step-by-step explanation:</u>
We know that:
First, we need to change the 'y' sign.
- => -y = -x + 6
- => y = x - 6
Now, let's compare both of the equations to find slope.
- => (y = x - 6) = (y = mx + b)
We can see that the slope is 1 and the y-intercept is -6.
<u>Conclusion:</u>
Therefore:
Hoped this helped.
9.5 because 9.5-7 is 2.5. 2.5 times 4/5 is 10/5 which is equivalent to 2. 4/5(2.5-7)=2
(i.) CA = πrl
CA = π (5*13)
CA = 65π
(ii.) TA = πrl + πr^2
TA = 65π + π (5^2)
TA = 65π + 25π
TA = 90π
(iii.) To get the height of the cone, you have to use the Pythagorean theorem. Plug in the radius for a and the slant height for c.
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169 Height = 12
b^2 = 144
b = 12
(iv.) v = (1/3)πr^2h
v = (1/3)π(5^2)*12
v = (1/3)π(25*12)
v = (1/3)π*300
v = 100π
