Answer:
500 cm2
Step-by-step explanation:
The dimensions of the prism are 7 cm, 9 cm and 20 cm.
So the three areas we want to find are three rectangles, with the sides:
7 cm and 20 cm, 9 cm and 20 cm, 9 cm and 20 cm
The area of each rectangle is:
rectangle_1 = 7 * 20 = 140 cm2
rectangle_2 = 9 * 20 = 180 cm2
rectangle_3 = 9 * 20 = 180 cm2
Summing all these three areas, we have:
Total area = 140 + 180 + 180 = 500 cm2
Answer: C. 13/24 i hope it help you out
Kali runs 30 laps in 3 days.
formula of a slope of a line when 2 points are given:
delta y/ delta x= slope -> y2-y1 / x2-x1= slope so:
8-4 / -1 +3
= 4/ 2
= 1/2
The equation for circumference is ( 2 * pi * R ), and the values can be multiplies in any order.
radius of 10 times 2 is 20
now we take 20 * pi (3.14)
which gives us <span>62.8318530718
then we round up to 68.8</span>
