Triangles are 180 degrees total so 80+40=120, subtract that from 180 and you’ll get B=60

The diameter is a circle is 16cm. Find it’s circumference in terms of π.<br><br> C= ________cm

Paraphin [41]

Answer:

Circumference of the circle = 100.53 in.

Step-by-step explanation:

Circumference of a circle is given by the formula,

Circumference = 2πr

Radius of the circle 'r' = 16 in.

Therefore, circumference of the circle with radius 16 in will be,

C = 2π(16)

C = 32π

C = 100.53 in.

3.Find the area of Triangle and Parallelogram having base 13.5cm and height is 18cm.

patriot [66]

Base=13.5cm
Height=18cm

$\\ \sf\longmapsto Area=\dfrac{1}{2}Base\times Height$

$\\ \sf\longmapsto Area=\dfrac{1}{2}(18)(13.5)$

$\\ \sf\longmapsto Area=9(13.5)$

$\\ \sf\longmapsto Area=121.5cm^2$

How do I go about solving (27x^3/8y^9)^5/3? And what is the role of the numerator and denominator?

MrRissso [65]

$\left( \frac{27x^3}{8y^9}\right)^ \frac{5}{3} \\\\\\ =\left( \frac{(3x)^3}{(2y^3)^3}\right)^ \frac{5}{3} \\\\\\ = \frac{(3x)^{3 \times \frac{5}{3} }}{(2y^3)^{3 \times \frac{5}{3} }} \\\\\\ =\frac{(3x)^5}{(2y^3)^{5 }} \\\\\\ =\frac{243x^5}{32y^{15}}$

Now, If the exponent was negative like you asked....

$\left( \frac{27x^3}{8y^9}\right)^ {-\frac{5}{3}} \\\\\\ =\left( \frac{8y^9}{27x^3}\right)^ {\frac{5}{3}}\\\\\\ =\left( \frac{(2y^3)^3}{(3x)^3}\right)^ \frac{5}{3} \\\\\\ = \frac{(2y^3)^{3 \times \frac{5}{3} }}{(3x)^{3 \times \frac{5}{3} }} \\\\\\ =\frac{(2y^3)^{5 }}{(3x)^5} \\\\\\ =\frac{32y^{15}}{243x^5}$
