If the area of a circle measures 16/25 π cm2, what is the circumference of the circle in terms of π? A) 5/8 π cm B) 4/5 π cm C)

xxTIMURxx [149]

Area=pi*r^2
16/25 therefore is r^2
therefore r=4/5
circumference = 2*pi*r
8*pi/5 is the circumference, C.

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:

$\implies 80 \pi = \pi r^2$

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

$\implies 80=r^2$

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

$\implies r=\sqrt{80}$

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

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

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

$\implies r=4\sqrt{5}$

You are cutting as many as 32 1/4 inch sections as you can out of a 129-inch board to make skateboards. How many skateboards can

SVETLANKA909090 [29]

You can make 4 skateboards because 1/4 is equal to 0.25 so therefore 32.25 is how big each section would be so in order to get the number of skate boards you divide 129 by 32.25 and that gets you the answer of 4
