Evaluate 10bc-b+c, when b = 3 and c= 2.<br><br> I need help ASAP!!!!!!!
Yuki888 [10]
I believe the answer is 59 .

first , you plug your variables into the equation : 10(3)(2) - (3) + (2) . next , you multiply the 10 and the 3 and the 2 to get : 60-3+2 . now , you add and subtract from left to right to get : 57+2 . now you add those and get 59 .

hope this helps :)

The area of a circle, in terms of π, is 80π m2. Find the value of the radius. Give your answer as a simplified surd.
jolli1 [7]

Answer:

r=4\sqrt{5}\:\: \sf m

Step-by-step explanation:

\textsf{Area of a circle}=\pi r^2 \quad \textsf{(where r is the radius)}

Given:

  • Area = 80π m²

Substitute the given value into the formula and solve for r:

\implies 80 \pi = \pi r^2

\implies \dfrac{80 \pi}{\pi} = \dfrac{\pi r^2}{\pi}

\implies 80=r^2

\implies \sqrt{r^2}=\sqrt{80}

\implies r=\sqrt{80}

\implies r=\sqrt{16 \cdot 5}

\implies r=\sqrt{16}\sqrt{5}

\implies r=\sqrt{4^2}\sqrt{5}

\implies r=4\sqrt{5}
