3 0

Circumference of a Circle,C=2πr

π=3.14
r= of the circle

Area of the circle= πr²

We know that
Area= 49 π²

πr²=49

r²=49/π
=49/3.14
=15.60
r= √15.60
=3.9 units

Circumference of a Circle,C=2πr
=2*3.14*3.9
=24.492 units

Nap ate 2/5 of the pizza Rowan ate 2/3 of the pizza that was left how much of the pizza did Rowan eat

kicyunya [14]

Answer:

Rowan ate $\frac{2}{5}$ of the pizza

Step-by-step explanation:

Nap ate 2/5 of the pizza Rowan ate 2/3 of the pizza that was left how much of the pizza did Rowan eat?

Nap: $\frac{2}{5}$ can be rewritten as $\frac{6}{15}$

Rowan: $\frac{2}{3}$ can be rewritten as $\frac{10}{15}$

After Nap ate 2/5 of the pizza, there is 3/5 pizza left.

$\frac{3}{5}$ can be rewritten as $\frac{9}{15}$

$\frac{9}{15}*\frac{10}{15}$ = $\frac{2}{5}$

$\frac{9}{15}*\frac{10}{15}=\frac{3}{5}*\frac{2}{3}=\frac{1}{5}*\frac{2}{1} =\frac{2}{5}$

Rowan ate $\frac{2}{5}$ of the pizza

Hope this helps!
