Answer:
2:1.
Step-by-step explanation:
The area of a red curved surface = 2πr^2.
The area of the yellow flat surface = πr^2.
This is the case for all the hemispheres.
Therefore the required ratio = 2πr^2 : πr^2
= 2:1.
Answer:
after 8years
Step-by-step explanation:
Complete question;
In what time will Rs 10000 will yield a compound interest of Rs 2769 at 3% per annum
Using the compound interest formula;
A =P(1+r)^n
Given
P = Rs10000
A = 10000+2769
A = 12769
rate = 3% = 0.03
Substitute and get the time t
12769 = 10000(1+0.03)^n
12769/10000 = 1.03^n
1.2769 = 1.03^n
log 1.2769 = nlog1.03
n = log 1.2769/log 1.03
n = 0.1062/0.01283
n = 8.27
Hence the time is approximately after 8years
Same side interior angles is the one you are looking for
B because 2/3 hours is 40 mins 40 x 5 = 200 200 is 3 hours and 20 mins which is 1/3
