A = 2πrh + 2πr^2 is the formula. Where A = surface area, r = radius, and h = height. So all we need to know is the outer radius, which is 3.5. Hope this helps you.
Answer:
y = 2x + 1
Step-by-step explanation:
1. Find the slope; (change in y values)/(change in x values)
Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2
2. Find the y-intercept (b) using the slope intercept formula: y = mx + b
m = 2 and using point (1, 3) , solve for "b"
y = mx + b
3 = 2(1) + b
3 = 2 + b
1 = b
3. Write the linear equation: y = 2x + 1
Answer:
Only one triangle can be constructed.
Step-by-step explanation:
We are given two side lengths of a triangle of 10 cm and 8 cm. The angle between the sides of the triangle measures 40°.
With the above-given data only one unique triangle can be constructed.
And the length of the third side can be calculated using the property of triangle as
a² = 10² + 8² - 2 × 10 × 8 Cos 40° {Where a is the length of the third side}
⇒ a² = 41.43
⇒ a = 6.44 cm. (Answer)
Answer:
A, n = (8 - 7p)/m.
Step-by-step explanation:
mn + 7p = 8
mn = 8 - 7p
n = (8 - 7p)/m.
180 - 72 = 118
And then the other way around is
72° again, makes the answer 118°.
