Question

ANSWER THIS JOHNCARL​

Answer 1

#2

• r=7cm

$\\ \sf\longmapsto Perimeter$

$\\ \sf\longmapsto 2\pi r$

$\\ \sf\longmapsto 2\times \dfrac{22}{7}(7)$

$\\ \sf\longmapsto 44cm$

And

$\\ \sf\longmapsto Area$

$\\ \sf\longmapsto \pi r^2$

$\\ \sf\longmapsto \dfrac{22}{7}(7)^2$

$\\ \sf\longmapsto 154cm^2$

#3

$\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{15}$

$\\ \sf\longmapsto x=\dfrac{60}{3}=20$

#4

$\\ \sf\longmapsto (a+5)(3a-6)$

$\\ \sf\longmapsto a(3a-6)+5(3a-6)$

$\\ \sf\longmapsto 3a^2-6a+15a-30$

$\\ \sf\longmapsto 3a^2+9a-30$

#5

$\\ \sf\longmapsto Area=64$

$\\ \sf\longmapsto side^2=64$

$\\ \sf\longmapsto side=\sqrt{64}$

$\\ \sf\longmapsto side=8cm$
