What is the area of the trapezoid? 80m2 96m2 100m2 120 m2

never [62]

Answer:

100m^2

Step-by-step explanation:

area of trapezoid formula: $({b_{1} +b_{2})}{1/2h}$

b=base

base #1= 8

base #2= 12

h(height)= 10

(8+12)=20(sum of bases)

20/2=10(sum of bases over 2)

10*10=100(height * whats remaining of bases)

100m^2

hope this helps

Write a proportion for 56% of a number is 244

Misha Larkins [42]

$\frac{56}{100} = \frac{244}{x}$ So, You cross multiply and get 56x=244(100). Simplify and you get 56x=24400. Divide each side by 56 and you get 435.71. 56% of about 435.71 is 244.

What is the area of the circle?

AlexFokin [52]

Answer:

530.93

Step-by-step explanation:

area of a circle = πr²

where r = radius

here we are given the diameter

to convert to radius , we divide by 2

so radius = 26 / 2 = 13

so we have A = πr²

==> plug in r = 13

A = π13²

==> evaluate exponent

A = 169π

==> multiply 169 and π

A = 530.93 ( approximately )
