Question

solve using the appropriate formula. hint: parallelogram: a = b · h find the area of a parallelogram with b = 4 cm. and h = 8 cm. solve using the appropriate formula. substitute 3.14 for π. hint: circle: a = π(r)^2 find the area of a circle with a radius of 4 cm.

Explanation:

Step1: Identify formula for parallelogram area

The formula for the area of a parallelogram is $A = b\times h$.

Step2: Substitute given values

Given $b = 4$ cm and $h=8$ cm, we substitute into the formula: $A = 4\times8$.

Step3: Calculate the area

$A = 32$ $cm^{2}$.

Step4: Identify formula for circle area

The formula for the area of a circle is $A=\pi r^{2}$, with $\pi = 3.14$ and $r = 4$ cm.

Step5: Substitute values for circle

$A=3.14\times4^{2}$.

Step6: Calculate circle area

First, $4^{2}=16$, then $A = 3.14\times16=50.24$ $cm^{2}$.

Answer:

The area of the parallelogram is 32 $cm^{2}$ and the area of the circle is 50.24 $cm^{2}$.
