Volume of one pyramid = 408.6*(755.9*755.9)*1/3
volume of 3 pyramids= 3*408.6*(755.9*755.9)=700,403,500.11*1/3=233,467,833.37
reasoning 3 square base pyramid = 1 cuboid
Answer:
160 in²
Step-by-step explanation:
The formula for the area of a triangle is ...
A = 1/2bh . . . . base length b, height h
Here, the triangle has a base length of 32 in, and a height of 10 in. Its area is ...
A = 1/2(32 in)(10 in) = 160 in²
Answer: you can find the area of a circle by multiplying the radius by pi and then squaring it by 2
Step-by-step explanation:
Answer:
$5225
Step-by-step explanation:
Use the formula for the amount after simple interest:
"A" is the final amount, or balance.
"P" is the principal, or the starting amount.
"r" is the rate of interest in decimal form.
"t" is the time.
What we know:
P = 5000
t = 3
r = 1.5%
Convert the rate to decimal form by dividing by 100, or moving the decimal place two places to the left.
1.5% => 0.015 = r
Substitute what we know into the formula:
A = P(1 + rt)
A = 5000(1 + (0.015)(3)) <=simplify
A = 5000(1 + 0.045)
A = 5000(1.045)
A = 5225 <= new balance
The new balance of an account is $5225.
