Answer:

Step-by-step explanation:

first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm

a = 48

b= 30

Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]

= 1/2*30√( 48² - 1/4×30²)

=1/2*30√ (2304 -225)

=684sq cm

cost required to make umbrella= 10*684*5

= 3<em>4200</em>

I NEED HELP NOOOOOWWWW!!!!!!!!
In-s [12.5K]

Answer: 1590cm^3

Step-by-step explanation:

V=\frac{3\sqrt{3} }{2}a^2h

a = base

h = height

V=\frac{3\sqrt{3} }{2}(6cm)^2(17cm)

Solve the parentheses squared first.

V=\frac{3\sqrt{3} }{2}(36cm^2)(17cm)

2 and 36 can be simplied

2/2=1

36/2=18

V=3\sqrt{3}(18cm^2)(17cm)

V=3\sqrt{3}(306cm^3)\\ V=1590.02cm^3

Rounded to the nearest whole number... 1590cm^3
